"This captivating and compelling action-adventure spectacle chronicles the saga of a heroic Thracian gladiator's rebellion against his Roman captors. In the Season 3 premiere, Spartacus (Liam McIntyre) sees his army grow and deal a serious blow to Rome's fighting legions, which leads Roman officials to seek empire-saving funding from the aristocratic and ambitious Marcus Crassus (Simon Merrells). Troubles continue to thwart Spartacus and his rebels, however, as they deal with food shortages, shelter problems, betrayals, mounting casualties and a spy in their midst. In the end, Spartacus and his outnumbered rebel force prepare for what could be their final, pivotal battle against the Romans."
