Alien from L.A.

A professor falls into a bottomless pit while digging for the lost subterranean world of Atlantis. His daughter, a plucky and pretty teenage girl, heads after him, and falls into the same pit...winding up in an upside-down world that thinks he's an alien. Soon the chase is on as the professor and his daughter try to make it back to the surface. (forgalmazó hivatalos szövege)
