Five years after The Chronicles of Riddick, Riddick has become increasingly uneasy in his role as Lord Marshall of the Necromonger fleet. His refusal to swear into the Necromonger faith has caused dissent among his subjects. Riddick strikes a deal with Commander Vaako; the location of Furya and a ship to take him there, in exchange for Vaako becoming the next Lord Marshall. Led by Vaako's aid, Krone, Riddick and a group of Necromongers arrive on a desolate planet. Recognizing 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.
Riddick manages to reset and splint his broken leg and fend off native predators; including Vulture and packs of Jackal-like beasts. Needing time to heal, Riddick sequesters himself within the ruins of a long-dead civilization. Riddick then surveys a vast savanna beyond some rocky cliffs, but the only passage through is guarded by a community of poisonous, scorpion-like creatures called "Mud Demons" which inhabit interposing muddy pools.
Two ships promptly arrive in answer to the beacon; the first a group of bush-league bounty hunters led by a violent and unstable man named Santana, and another better-equipped team of professional mercenaries led by a man named Boss Johns. Riddick later manages to steal power nodes from each of the teams' ships and then approaches Johns and Santana to strike a deal for their return. However, the conversation turns out to be an ambush. Johns' second-in-command, Dahl, shoots Riddick with powerful tranquilizers. In an effort to defend his master, Riddick's alien jackal brutally attacks Santana, but is shot multiple times in the throat.
Back at the Merc Station, Johns interrogates Riddick about the final fate of his son, William J. Johns. When the storms finally reach the station, large numbers of Mud Demons emerge from the muddy ground, and besiege the station, killing Lockspur and Moss. Johns agrees to release Riddick in order to locate the hidden power cells. Santana stops him and attempts to kill Riddick, who is worth twice as much dead as he is alive. Riddick instead beheads Santana with severe prejudice for killing his animal companion.
They then fight their way to the ship which houses the hover bikes with Vargas being killed. Johns, Santana's man Diaz, and Riddick leave the ship together on hover bikes on a mission to retrieve the power nodes. During their journey, Johns crashed his bike to the terrain and is rescued by Riddick. With both of them distracted, Diaz attempts to kill Riddick and Johns. Riddick fights and kills him, but not before unintentionally damaging the only working hover bike (Diaz had already disabled the other one).
Riddick and Boss Johns fend off a seemingly endless horde of Demons while running back to the station. Riddick is severely wounded. Johns takes both nodes and abandons Riddick. After treating his wound, Riddick begins to fight a futile battle against the advancing Demons. Just when it seems he is about to be killed, Johns arrives in one of the ships and shoots the creatures while Dahl descends to rescue Riddick. Riddick then takes the other ship and as he flies away from the planet, he is stopped by Johns in the other ship. Johns asks Riddick where he will go, but thinks better and decides to not know. Riddick praises Johns for being a better man than his son and departs into deep space.
It takes awhile for me to understand the whole movie because I did not watch the previous sequel. Nevertheless, this movie isn't that bad and I can see how much Vin Diesel love his dog companion when he found that he was shot to death. Aww... Anyway, I'll rate the movie: 3.5/5.
