In his 1991 feature directorial debut, Michael Tolkin has made an unsettling film of theological ideas intent on looking into what we believe and why we believe it. The movie is determined, even eager, to explore the most basic issues of heaven, hell and the hereafter. Improbable as it sounds, Tolkin has blended the question of whether God or chaos rules our universe into the format of a sensual thriller. Mimi Rogers turns in an astonishingly stunning performance as a woman stuck in a dull day job who turns swinger at night. Kimberly Cullum plays the daughter born after Rogers' religious conversion (Bravo Saturday at 6 and 10 p.m.).
