A scientist, a reporter and a repairman are accidentally transported to a prehistoric world in a parallel universe when they fall into the beam of the experiment during an earthquake aftershock. It's a cheaply made fantasy/adventure romp that doesn't take itself too seriously, as evidenced by the sound effects that fall somewhere between The Three Stooges and a Kung Fu flick. You'll have no trouble telling the good guys from the bad guys in this simple morality tale.
