Tim Matheson and Oscar nominees Meg Tilly and Hume Cronyn come face to face with mankind's deepest-and darkest-primal urges in this disturbing and "suspenseful" (Boxoffice) psychological thriller. "Directed with flair" (The Hollywood Reporter) and packed with pulse-quickening twists that spring from its "terrific premise" (The Village Voice), Impulse generates enough electricity to make your hair stand on end!
When Jennifer (Tilly) and her boyfriend Stuart (Matheson) return to her idyllic hometown, they discover that all boundaries of civility seem to have eroded. Mystified by the actions of normally kind townspeople who are suddenly driven to extremes of irrational-and violent-behavior, Jennifer and Stuart attempt to get to the bottom of the increasingly life-threatening chaos...before it destroys them!
