This is the story of two teenagers who discover a time-machine buried in their back yard. It turns out to be a bit more complicated than that, spawning time-paradoxes and a wild adventure back to the time of dinosaurs, the ice-age, and eventually to the time of Jesus.
Both kids end up learning valuable life-lessons. Daniel learns to overcome the school bullies with Emma's help, and eventually learns to forgive them. Daniel and Emma are constantly arguing about religion, since Daniel is an Atheist and Emma is the daughter of a Pastor. In the end, they discover they were both right and both wrong.
This story is unique in that it really gets into a lot of science and technology, but unlike Hollywood movies, the science in this movie is text-book accurate. There is also a lot of Christian theology in this story, but isn't preachy or in-your-face.
The heart of this story is really a tale of adventure. As they become lost in time and space, they have to learn to depend on each other to find their way back to the present, overcoming many challenges along the way.
