Worlds collide at an awkward dinner party in 1959 New England. Tables turn when a progressive biracial couple attends dinner at the imposing home of an unexceptional artist and questionable psychiatrist. By daybreak, they find themselves pawns in a cynical game that exposes the cracks in their facades.
A bereaved Satanist couple kidnap a pregnant woman so they can use an ancient spellbook to put their dead grandson's spirit into her unborn child, but they end up summoning more than they bargained for.
