Brennac, a hospital shrink, recaps the case of Claude for a video camera, a patient he has agreed to see at the urging of his friend and fellow shrink, Karl. In daily sessions, Claude reveals a handful of distinct identities, all with names drawn from Greek mythology. Not long after Karl unearths the trauma that probably generated his patient's multiple personalities, Matthias, a police inspector, hits on a morbid piece of the puzzle. But the solution is still out of reach.
