Spartacus: War of the Damned Season 3

Furius and Cossinius can't capture the rebel slaves army, nor properly keep their plans secret. Realizing hiding will be much harder in winter, Spartacus decides to capture a town. First he and a trusted band sneak up to the commanders' hideout villa to slay them. The senate fears Rome itself may be endangered but lacks funds and men to mount a suitably large army. So Metellus turns to immensely rich, ambitious Marcus Crassus, who accepts, to eager son Tiberius's frustration without even negotiating an accordingly exalted status or mandate, and continuous private sparring with a dearly paid gladiator, whom he ends up killing in a fair duel. Spartacus's victory unwittingly plays into Crassus's hand, as he now formally 'inherits' sole command.
