At the 1972 Summer Olympics in Munich, the Palestinian terrorist group Black September kills 11 members of the Israeli Olympic team. Avner Kaufman, a Mossad agent of German-Jewish descent, is chosen to lead a mission to assassinate 11 Palestinians allegedly involved in the massacre. At the direction of his handler Ephraim, to give the Israeli government plausible deniability, Kaufman resigns from Mossad and operates with no official ties to Israel. His team includes four Jewish volunteers from around the world: South African driver Steve, Belgian toy-maker and explosives expert Robert, former Israeli soldier and "cleaner" Carl, and Danish document forger Hans. They are given information by a French informant, Louis.
