It is the year 2425. Nature has taken back control of the earth centuries after a disastrous meteor crash. Young Ocean Mooney and the monkey-owning Duke Smiff have recently discovered a 400-year-old tablet computer in a little town in what was once England. The Time Tablet, a tool they hope will enable them to interact with the future, is created by Thomas Reeve and his brilliant cousin Kylie in the present. But, Thomas and Kylie are transported into the year 2425 when the Time Tablet malfunctions live on television. They have just 24 hours to get home and save civilization.
