The suburbs - manicured lawns, palatial houses, car pools, wife swapping and murder. Even the most picturesque suburb can hold dark secrets in its lush gardens. Detective Inspector Kate 'Ash' Ashurst (Caroline Catz, The Vice) and Detective Sergeant Emma "Scribbs'" Scribbins (Lisa Faulkner, New Street Law) are partners who investigate crimes in Middleford Criminal Investigative Department.

In Series One the detectives investigate six cases ranging from a singles club murder to an out-of-control stag party and a home improvements lover whose hammer becomes a murder weapon.
