A startling encounter on a New York subway platform leads two strangers to a run-down tenement where a life or death decision must be made. In that small apartment, “Black” and “White,” as the two men are known, begin a conversation that leads each back through his own history, mining the origins of two fundamentally opposing world views. White is a professor whose seemingly enviable existence of relative ease has left him nonetheless in despair. Black, an ex-con and ex-addict, is the more hopeful of the men–though he is just as desperate to convince White of the power of faith as White is desperate to deny it.
