Impulse

In this 1974 psychological drama, William Shatner stars as Matt Stone, a troubled conman who seduces lonely women and kills them for their savings. As he sets his sights on a new target, a widow and her preteen daughter become suspicious of his motives, leading to a violent showdown that exposes the darker side of this charismatic predator. Shot in just 15 days with a subdued filmmaking style, Impulse is a tense thriller with bits of romance, but its graphic violence and dark themes have made it a notorious misfire for Shatner's career.
