Darkman III: Die Darkman Die

Scientist Peyton Westlake, aka Darkman, seeks to create a permanent liquid-skin formula to mend his burned face and body. He interrupts a criminal exchange spearheaded by power-hungry businessman Peter Rooker, who becomes fascinated by Westlake's superhuman strength and agility. Rooker steals Westlake's research and uses him as a guinea pig to replicate the perpetual adrenal overload that gives him his power, but Westlake escapes and eventually assumes Rooker's identity to be a loving father and husband. In a thrilling showdown, Westlake ultimately defeats Rooker and saves his family, then decides to use the liquid skin to repair his own face rather than his daughter's.
