Impulse (2008)

Synopsis: A woman seeking to revive the spark in her marriage inadvertently attracts the attentions of a stranger with a twisted concept of romance. Claire Dennison (Willa Ford) is a passionate beauty who has grown increasingly distant from her once-loving husband. But Claire is intent on arousing her husband's dormant desires, and plans an elaborate role-playing game in order to make that happen. At first it appears as if her husband is playing along as planned, but it doesn't take long for Claire to discover that she's playing with fire. The man she has attracted is in fact a total stranger, and by the time she tries to break things off it may already be too late.     Source: Sony Pictures Home Entertainment
