A team of biomechanically enhanced people from the future have traveled back to the 20th century to prevent a disaster of epic proportions. The form that they take, however, makes them appear as teenagers, and so the only way for them to blend into society is as exchange students. The secret will be hard to keep -- especially with a nosy host mother, but it is imperative that they succeed in both finding the event that will hurl the Earth into turmoil and stopping it as well.
