Skin Deep (2003)

The two black men (Anthony and Michael) are successful in the high tech world of Silicon Valley, and have known each other since childhood. The story takes place over the course of a day, when the couples get together for an afternoon of dining, drinking, and hot tubbing. Later, one of the wives is found dead in the hot tub, setting off a series of events that reveal their inner beliefs. Things turn dark as racism, paranoia, and the mistress come into play. This results in more deaths, until the ultimate realization that your thoughts and actions are more important than the color of your skin.
