After arriving at Deep Space 9, Ibudan, a Bajoran murderer recently released from prison, tangles with Security Chief Odo. When Ibudan is murdered in a holosuite, the evidence points to a shapeshifter as the guilty party. Odo, who had vowed to remove Ibudan from Deep Space 9 at any cost, is accused of the crime. Soon an angry group of Bajorans comes looking for justice and Commander Sisko is forced to relieve Odo of duty.
