 A woman takes her children to see their uncle, who is a scientist working on cryogenics experiments. They are using monkeys and other primates in their experiments. There is an earthquake, and the woman and her kids are trapped in cryogenic chambers and are somehow transported into a _Planet of the Apes_ type futures. They are captured, escape, return to the present and are eventually given an explanation of what happened to them that is incomprehensible. Also, this is really a re-edited Japanese TV series, so there s some odd continuity bits, especially near the end.
