Fans of Vin Diesel's intergalactic serial killer Richard B. Riddick have been pretty excited these past few months, thanks to the news that the actor will be returning to the character in an all new story written and directed by "Pitch Black" helmer David Twohy. Details have been scant so far, but today brings a paragraph-long plot synopsis. And it sounds pretty cool. The story opens with Riddick betrayed and left for dead on a remote world. Only he's got plans of his own, and no one beats down the galaxy's baddest killer that easily. Check out the full synopsis over at Shock Till You Drop.
