Fatal Exposure

At the Neurology Institute, Dr. Tom Redding (Marc Singer) and Dr. Freddie Summers (David Kagen) study brain responses to sexual and non-sexual stimuli, where Tom meets the alluring Dr. Claire Archer (Lisa Pescia), an expert in the biology of aggression whose research proposal impresses their boss, Dr. Pritchard (Joseph Campanella). While Tom is married to Marlee (Mary Crosby), Claire seduces him during a late-night lab session, and their affair escalates rapidly. Tom attempts to hide the relationship, but Claire becomes increasingly possessive, manipulative, and entangled in both his professional life and his home, forcing him into deeper lies as she pressures him to continue the affair. When Tom tries to break things off, Claire retaliates with escalating psychological warfare. She sends disturbing packages to his home, records their encounters, and threatens his career and family. Her fixation grows dangerous: she appears unexpectedly, coerces him into further sexual encounters, and begins invading his family's space - including sending a sex tape disguised as a children's video to Tom's young son. Tom becomes desperate, lashing out violently at her, which only deepens Claire's conviction that their shared “chemistry” is inescapable. As Tom and Marlee's marriage deteriorates, Claire boldly inserts herself into their social circle, culminating in her arrival at a celebratory dinner party as Freddie's date. Marlee overhears Tom threatening Claire, realizes he has been lying for months, and orders him out. That night, Claire returns to the house, sets a fire, and sends the family into chaos. Tom confronts her, but the encounter ends with Claire shooting him and later claiming he was a dangerous, obsessive lover who refused to end the affair. When the police leave, Claire collapses in private grief.
