Simon Mitchell was a successful and powerful criminal defense attorney, the kind of man accustomed to having a jury or a woman see things his way. Then sex psychologist Dr. Claire Archer (Shannon Tweed) walks into his office, accused of murder. To his surprise, he's strongly attracted to his new client. Powerless to resist her, he's rapidly drawn into an ever-tightening web of obsession, lust and betrayal. Now, with both his marriage and career on the rocks, he may have to give up something more valuable. Because saving the life of this sexual predator could easily cost him his own.
