She's his friend, his co-worker... and his best friend Miles's wife. He succumbs and they both give in to the insatiable fire of adultery, but the mind-blowing tryst was nothing more than a treacherous charade that unravels his career, marriage and friendships. Now his obsession and sexual escapades threaten to ruin all he's worked so hard for, trapping him deeper into a web of illicit desire, deceit and danger.
