The West Wing and Parks and Recreation alum -- who is also an executive producer on the project -- plays American lawman Bill Hixon, who has been appointed chief constable of the East Lincolnshire Police Force.
"Landing in Boston, Lincolnshire with teenage daughter Kelsey, he's hoping they can flee their recent painful past. However, this unfamiliar, unimpressed community will force Bill to question everything about himself and leave him wondering if it's Boston that needs Bill, or Bill that needs Boston?" a press release said.
The show co-stars Rachael Stirling, Tony Pitts, Bronwyn James and Angela Griffin.
