This spin-off from Death in Paradise follows DI Humphrey Goodman and his fiance, Martha, as they leave London to start a new life on the Devon coast. Humphrey takes up the vacant position of Detective Inspector at Shipton Abbott police station, a slightly antiquated outpost of the Devon & Cornwall Police district. Meanwhile, Martha's keen to open up her own cafe. Both are hoping for a quiet lifestyle away from the stress and violence of the city. But it doesn't take long for the couple to realise that countryside life is not going to be so quiet after all. For one thing - there's the surprisingly high crime rate to contend with.
