Set in Wales, Death Valley follows the unlikely crime-solving partnership between eccentric national treasure John Chapel (Spall), a retired actor and star of hit fictional detective TV show Caesar, and disarming detective sergeant Janie Mallowan (Keyworth). Thrown together by the murder of John’s neighbor, John and Janie are an odd, yet hilarious duo with opposing instincts, and each week they get to the bottom of gripping murders.
The third season began on March 14, 2009 with the three-part premiere, Transwarped, and ended on May 23, 2009. This season following the events of Transwarped focused on the Autobots' attempt to reach Cybertron in order to warn the Autobot High Council of Shockwave, who has been masquerading as Autobot Intelligence Officer Longarm Prime. Meanwhile, Megatron, Starscream, Shockwave (who replaces Blitzwing as a main character), and Lugnut plan to use the colossal Autobot Omega Supreme for constructing clones of him (dubbed as Lugnut Supremes, as they appear similar to Lugnut).
