Chameleon (movie, 2008)

While cleaning offices at night, Zsolt Kovàcs learns a lot about his invisible employers by examining what they leave behind, carefully choosing his targets, often disillusioned women whom he seduces, methodically taking their money. An artist of manipulation, with a generous dose of humor and the ability to assume different personalities, Zsolt begins to work in a psychologist's practice, where he meets Hanna, a 30 year-old dancer who is physically incapacitated and the daughter of a millionaire. The ideal victim if love doesn't get in the way.
