In Fahrenheit, New York City is stunned by a series of mysterious murders, all following the same pattern: ordinary people are killing absolute strangers in public areas. Lucas Kane becomes another one of these murderers when he suddenly kills a stranger in a men's washroom. Covered in blood, Lucas regains consciousness with no recollection as to why he committed the murder. Hunted by police, Lucas must solve the mystery before being caught and incarcerated for life.

A free-flowing game during which players can assume the role of multiple characters and experience the game from multiple viewpoints, Fahrenheit allows players' actions to affect the plot by offering a scenario driven interactive experience. Through motion picture techniques such as actor direction, multi-camera views, motion tracking and a contextual music score, players find themselves intimately immersed in the game.
