The gorgeous and sexy Claire Dennison (Willa Ford) is the successful manager of the advertisement agency Image Engine and married and in love with the middle-aged psychologist Jonathan Dennison (Angus Macfadyen). Their life is perfect but Jonathan is not good in bed, frustrating Claire's desires. When a colleague suggests Claire to fantasize with Jonathan to bring passion to their relationship and have kinky sex with her husband, she pretends to be a sexy Italian but Jonathan does not participate in the game, and Claire asks him "to play the Italian lover Robert" in the future. When Claire travels in a job assignment, she sees Jonathan fashionably dressed and wearing a different hair style in the hotel lobby and she drags him to her room and has kinky sex with him. Then they schedule through e-mail a next encounter in New York; in the morning, Jonathan calls Claire in the cell phone and she realizes that the man on her bed is a complete stranger. Sooner the man stalks Claire and introduces himself to her as Simon Phillips; she discovers that the Simon is psychopath obsessed for her and jeopardizing her married life.
"Impulse" has an absurd plot, and only if the viewer believes in perfect doubles and coincidences he or she may like this flick. There is no credibility in the story and in the characters. Claire is a sexy woman in the top of her professional career but has a monotonous life with her husband. It is hard to believe that a woman like Willa Ford be in deep love with an unattractive, boring and fat man like Jonathan. Then she meets Wilson in a work trip and in her hunger she does not recognize any difference between Jonathan and Wilson. Is that possible, smell, voice, sex, everything identical in two men that are not siblings? Last but not the least, Simon could not know details of Jonathan's personal life, therefore Jonathan being arrested claiming to be himself and his situation in the mental institution are simply ridiculous. Then the plot becomes the conventional story that every Saturday the broadcast TV transmit, with a psychopath stalking a family etc. My vote is four.
