This starts off with a sequence of a woman narrating and showing the crew of the ship in their pods as they enter what looks like Saturn’s atmosphere. So for some reason they crash on the planet and much of the crew is dead, but what’s left of the crew must survive. But there’s one problem, the vicious criminal they had captive in the ship has escaped and is on the run. The crew is looking for him, but strange things start happening as they scour the planet. They discover creatures that inhabit the planet. They live in the dark. They’re safe for now because the planet has three suns… or are they?
