Last week we reported that another adventure in David Twohy and Vin Diesel's Richard Riddick saga was moving forward and now we have a few new tidbits on the story. According to The Hollywood Reporter, in a story on the film's sales run at the European Film Market, the first plot details for the Untitled Chronicles of Riddick Sequel have been revealed.

Though billed as a back-to-basics approach to the character popularized by Diesel, the script features the character -- the most wanted man in the galaxy -- left for dead on a barren alien planet, dealing with "trisons" (three-legged bisons) and "mud demons." He must then contend with two squads of bounty hunters, one of which ride rockets called jetcycles.

Vin Diesel will reprise his role as Riddick, which he played in both Pitch Black and The Chronicles of Riddick, and David Twohy, directed both films, will write and direct this third film.
