This is actually a pretty good TV movie, based on a true story, starring real life husband and wife, Harry Hamlin and Lisa Rinna. Hamlin plays a sex addict who gets caught cheating by his wife. It turns out to be a little more than cheating, and Hamlin's chronic problem is ultimately exposed. He basically destroys his marriage, as well as his relationship with his children.
The indication that this film is realistic and based on a true story is the fact that Hamlin's wife keeps taking him back despite his many transgressions.
The movie doesn't pull any punches - it explores treatment options, 12 step programs, problems that Hamlin's own father had, and the difficulty that husband, wife, and family have coming to terms with their difficulties. It also shows the gritty situations that the man gets into, making one realize that only a compulsive personality would put himself through such horror. Hamlin and Rinna do a very good job.
