Rose Tyler and the twin detectives

Alec Hardy wants to return to the Broadchurch Police but has already been replaced so he gets on a plane to a small town in the US called Gracepoint to work with Det. Emmett Carver unaware he is the man's double. The fun starts as they disagree over everything and fight over Rose Tyler, who is working in the town as a reporter, undercover for Torchwood. Crossover with Broadchurch.
