Nick Berry and Stephen Tompkinson return for a second series of the hard-hitting BBC crime drama, 'In Deep'. Liam (Nick Berry) and Garth (Tompkinson) go deep undercover, as they tackle the sinister world of a big-time drug dealer (played by Ian McShane). as well as contract killings, kidnapping and preventing another murder by a potential serial killer. Garth is left fighting for his life, whilst Liam's relationship with his wife (Lisa Maxwell) is at an all-time low. Complex and unpredictable. In Deep is high quality drama dealing with the psychological issues that lie beneath the surface of being a crime detective.
