Plot: Five years after Kyra's death, Riddick has become increasingly uneasy in his role as Lord Marshal of the Necromonger fleet. His refusal to swear into the Necromonger faith has caused dissent among his subjects and assassination attempts by his subordinates. After the latest attempt on his life, Riddick strikes a deal with Commander Vaako: the location of Furya and a ship to take him there, in exchange for Vaako succeeding him as the next Lord Marshal, so that he can achieve what he calls transcendence. Led by Vaako's aide, Krone, Riddick and a group of Necromongers arrive on a desolate planet. Realizing that it is not Furya, Riddick kills most of his escort when they attempt to assassinate him. In the chaos, Krone causes a landslide and buries Riddick alive..
Alternative Plot: Left for dead on a sun-scorched planet, fugitive Riddick (Vin Diesel) fights for survival against alien predators more lethal than any human he has yet encountered. His only hope for escape is to activate an emergency beacon, but that brings with it a different problem: mercenaries. The first ship carries an especially violent and lethal group; the second is led by a man from Riddick's past. With time running out, Riddick realizes that neither group will leave without his head as trophy.
