A race of off-camera, thumbless, time-traveling alien "Masters" kidnaps thumb-bearing humans from Earth's future to use as slaves and takes dinosaur puppets from its past to use as trackers of those who escape. One of their victims, the Runaway (Daniel Bernhardt) escapes in a "Neutrogena bar" from another movie and arrives in late 1990's Los Angeles.
