The space transport vessel Hunter-Gratzner carrying 40 people on-board crashes on a desert planet when the ship is struck in a meteor storm. There are only 10 survivors, among them are pilot Carolyn Fry (Who has assumed command after the ship's captain is killed), bounty hunter William J. Johns, religious man Abu Al-Walid, Antiques dealer Paris P. Ogilvie, runaway teenager Jack, settlers John 'Zeke' Ezekiel and his lover Sharon 'Shazza' Montgomery and Richard B. Riddick, a dangerous escaped convict. Marooned, the 10 survivors finds the barren and hot desert-scape has sunlight from three suns. Not only they find food and water, and worry about Riddick, the survivors finds themselves being hunted by the planet's flesh eating alien inhabits, when the planet is engulfed in darkness, which happens every 22 years, as they come out on to the surface to hunt and eat all signs of life. Fry and the survivors find Riddick is their best chance of survival, as Riddick has surgically-enhanced eyes that allow him to see in the dark as they set out to find a way of escaping from the planet and getting to a escape shuttle, before they all get eaten by the creatures on the surface.Set in the distant future, a spaceship carrying some 40 people, mostly ones wanting to settle on other planets from their own, hits a meteor shower and crash lands on a distant planet killing all but ten of them. The survivors, led by the second-in-command Carolyn Fry ('Rahda Mitchell' ), find themselves on a hot and arid landscape with constant sunlight from three orbiting suns. Fry not only must help the survivors find food and water, but contend with a deadly criminal, named Riddick (Vin Diesel), who was being transported to a prison cell on their destination. But every 22 years, the planet's three suns go into a total eclipse for a month where darkness brings out the planet's real inhabitants; large, reptilian, vampire-like creatures that come out and dominate the surface in total darkness, killing and eating all life. The Fry and her people then must cooperate with Riddick, who has surgically enhanced eyes to see in darkness, to lead them to safety and off the planet before they all become dinner for the creatures.
