Plugged In exists to shine a light on the world of popular entertainment while giving you and your family the essential tools you need to understand, navigate and impact the culture in which we live. Through reviews, articles and discussions, we want to spark intellectual thought, spiritual growth and a desire to follow the command of Colossians 2:8: "See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the basic principles of this world rather than on Christ."


Family uses Plugged In as a ‘significant compass’

"I am at a loss for words to adequately express how much it means to my husband and me to know that there is an organization like Focus that is rooting for us. Just today I was reading Psalm 37 and thinking about how your ministry provides ways to 'dwell in the land and enjoy safe pasture.' We have two teenagers and an 8-year-old in our household...Plugged In has become a significant compass for our family. All three of our kids are dedicated to their walk with Christ but they still encounter challenges. Thanks for all of your research and persistence in helping us navigate through stormy waters."

Plugged In helps college student stand-up for his belief

"Thanks for the great job you do in posting movie and television reviews online. I’m a college freshman and I recently had a confrontational disagreement with my English professor regarding an R-rated film. It is her favorite movie and she wanted to show it in class. I went to your Web site to research the film’s content. Although I had not seen the movie myself, I was able to make an educated argument against it based on the concerns you outlined. The prof said that she was impressed by my stand and decided to poll the whole class and give us a choice. We overwhelmingly voted to watch a G-rated movie instead! I’ve learned that I can trust your site and I will be using it a lot in the future.”

Plugged In brings ‘Sanity and Order’ to Non-believer

“Even though I don’t consider myself a Christian, I find your Plugged In Web site useful and thought-provoking. No one reviews movies like you do. Instead of being judgmental, you put entertainment ‘on trial.’ After presenting the evidence, you allow the jury of your readers to decide for themselves what they should do. In my opinion, you bring sanity and order to the wild world of modern day entertainment. Keep up the good work!”

Mom thinks Plugged In is the ‘BEST Christian media review site’

"Our family doesn't go to the movies until we go online and check out your assessment of a given film. I think this is the BEST Christian media review website that I've found, and I recommend it to my family and friends. Keep up the good work!"


Our hope is that whether you're a parent, youth leader or teen, the information and tools at Plugged In will help you and your family make appropriate media decisions. We are privileged to do the work we do, and are continually thankful for the generosity and support from you, our loyal readers, listeners and friends.

Plot Summary

A prologue explains the history of the magic tree house that Jack and his sister, Annie, have discovered. By touching a picture in one of the many books inside the tree house, the children are instantly transported from Frog Creek, Pa., to other time periods and places. So far, they have encountered dinosaurs, knights, pirates and an Egyptian mummy. They have also met an enchantress from the days of King Arthur named Morgan Le Fey, who travels through time to collect books for the tree house.

After several days of looking for the tree house, the children believe that it has disappeared. They are sad that they may never see Morgan again. Then one evening as they're walking through the woods, Annie sees it, and they both climb up the rope ladder. Inside the tree house, they meet a tiny mouse that Annie names Peanut.

Jack finds a piece of paper on the floor that seems to be a note from Morgan. It says that she needs help because she is under a spell. The children notice that a library book has been left open to a picture featuring two ninjas wearing swords and black scarves over their faces. Annie thinks Morgan is in trouble with the ninjas and wants to help rescue her. Before Jack can grab the book from her, Annie points to the picture and wishes that the tree house would take them to meet the ninjas. The wind begins to blow. When it stops, Jack and Annie find themselves in Japan, hundreds of years ago.

Through the tree house window, the children see two ninjas. Jack warns his sister not to let them see her because they might think she's an enemy. Jack reads from the book that ninjas were warriors in the 14th to the 17th centuries. They fought to protect their families and were sometimes spies. Ninjas could be male or female. Jack copies this information in his notebook. Suddenly the children hear the ninja cry out. Terrified, they pull up the rope ladder, but the ninjas climb the tree trunk like cats and enter the tree house.

Annie shows them Morgan's note and tells the ninjas that they (Annie and Jack) are trying to help her. The short ninja takes the note and points to the rope ladder, indicating that the children should climb down it. Annie puts Peanut in the pocket of her sweatshirt, and they follow the ninjas down the ladder. The ninjas lead the children to a rushing stream of freezing cold water. Jack wants to run back to the tree house, but Annie persuades him to cross it for Morgan's sake. The water is so cold that the children can't cross without help, so the ninjas offer to carry the children on their shoulders.

By the light of a full moon, the children follow the ninjas through a forest until one of them holds up his hand, indicating that they should wait. The ninjas disappear. Jack reads in the library book that ninjas sometimes hold meetings in hidden caves and take orders from a ninja master, who was usually a nature expert. He writes this information in his journal. Soon the ninjas return and motion for Jack and Annie to follow them into a cave.

A ninja master is sitting on a mat in the cave. He tells the children to sit down. They explain that they are on a quest to help Morgan. The ninja master tells them that he can help them, but first they must prove themselves worthy. He explains that his family is at war with some samurai fighters. To prove their worth, the children must find their way back through the dark forest alone and avoid the samurai. He tells them to use nature, be nature and follow nature. Jack writes these instructions in his journal.

The children draw up their sweatshirt hoods so they look more like ninjas. In order to figure out which direction to go, Jack uses nature. He tells Annie to find a stick. He holds it up in the moonlight to create a shadow. The shadow helps them determine the direction of east. Then he searches the library book for more information and finds that samurai carry two swords to combat their enemies. When he looks up, he sees a giant warrior carrying two swords. Annie remembers the master's instruction to "be nature" and tells Jack to be as still as a rock. They both freeze and wait until the warrior leaves.

To reach the tree house, Jack and Annie must cross the cold river again. Just as they begin to cross, Peanut jumps from Annie's pocket and scampers away. Annie reminds Jack that the master said they must follow nature, so they follow Peanut to a branch that crosses the river. When they arrive back at the tree house, they find the ninja master waiting for them. He tells the children that they have done a good job and gives them a moonstone, one of the four items that will help them break Morgan's spell. He reminds them to keep a kind heart.

The children touch a picture of Frog Creek, and the tree house spins them back home. Their mother is calling them for dinner. Annie makes a bed for Peanut out of one of her socks, and the children thank the mouse for helping them on their journey.

Christian Beliefs


Other Belief Systems

The tree house is a magic place that the children can see but others can't. Morgan le Fay is an enchantress. Her magic allows the tree house to transport the children through time and to the places they find in the books that are in the tree house. She is its owner. Annie is able to see the tree house because she believes in magic. In a previous book, Morgan le Fay became trapped by a magic spell. She needs four items to break the spell. The children travel through time to find those items for her.

One of the ninja master's rules for living is to "be nature." Jack and Annie pretend to be stones when they are in the presence of the samurai, and they believe that this practice saves their lives. They are told to follow nature, too, so they follow Peanut, a mouse, across the river and back to the tree house.

Authority Roles

The Japanese ninja master commands respect from the children. When he tells them to sit down or to explain why they have come to see him, they obey. They remember the three rules of living like a ninja and practice them on their way back to the tree house.
