Left for dead on a sun-scorched planet, Riddick finds himself up against an alien race of predators. Activating an emergency beacon alerts two ships: one carrying a new breed of mercenary, the other captained by a man from Riddick's past.

The wanted criminal Richard Bruno Riddick arrives on a planet called Helion Prime and finds himself up against an invading empire called the Necromongers, an army that plans to convert or kill all humans in the universe.

Newly-paroled former US Army ranger Cameron Poe is headed back to his wife, but must fly home aboard a prison transport flight dubbed "Jailbird" taking the “worst of the worst” prisoners, a group described as “pure predators”, to a new super-prison. Poe faces impossible odds when the transport plane is skyjacked mid-flight by the most vicious criminals in the country led by the mastermind — genius serial killer Cyrus "The Virus" Grissom, and backed by black militant Diamond Dog and psychopath Billy Bedlam.

A commercial transport ship and its crew are marooned on a planet full of bloodthirsty creatures that only come out to feast at night. But then, they learn that a month-long eclipse is about to occur.
