Half man, half monkey, Chad was born in a lab and kept hidden from the world. A journalist, investigating a macabre mass-murder, discovers the mutant boy — a creature with the mind of a child and superhuman strength. But the reporter finds out the hard way that nothing, and nobody, can stand in the way of progress. (Re-titled for its American VHS release, "Monkey Boy" is an abbreviated film version of Lawrence Gordon Clark's 1991 mini-series "Chimera".)
