Darkman

Scientist Peyton Westlake (Neeson) is developing a new type of synthetic skin to aid burn victims. He is frustrated with a flaw in the "skin", which causes it to rapidly disintegrate after being exposed to light for 99 minutes; however, it remains intact in darkness. Despite his devotion to the project, he cannot get past this limitation.Westlake's girlfriend, attorney Julie Hastings (McDormand), comes upon an incriminating document proving that corrupt developer Louis Strack Jr. (Friels) and mobster Robert G. Durant (Drake) have been giving bribes to members of the zoning commission. In search of the document, Durant and his minions attack and injure Westlake, retrieve the document, then blow up his lab. The blast throws Westlake clear of the lab and into the river across from it; he survives but is hideously burned. He is brought to a hospital and subjected to a radical treatment in which the nerves of the spinothalamic tract are cut so as not to feel the pain. Removing this sensory input gives him enhanced strength due to adrenal overload and keeps his injuries from incapacitating him, but it also destabilizes his moods and mental state.Westlake escapes the hospital and sets out to get revenge on Strack and Durant. He also seeks to re-establish his relationship with Hastings. To hide his scarring and blend into crowds, Westlake rebuilds enough of his equipment to make his synthetic skin, but is still unable to overcome the 99-minute window of integrity. Thus, he can only appear briefly in public as himself (or later as others, whose features he is able to duplicate) in daylight, and otherwise wears bandages and a trenchcoat in his identity as Darkman. He is able to make masks in advance and store them for long periods by keeping them from light sources. He takes the opportunity to observe important people, such as his enemies, so he can masquerade as them.Westlake eventually succeeds in destroying his enemies but is unable to return to his old life and thus continues his existence as Darkman. Running away from Julie as they leave an elevator, Westlake is seen from behind putting on a mask which, as seen in the final shot of the movie, is the face of Bruce Campbell.
