Set in 1981, everyone's favourite politically incorrect cop, flanked by his faithful sidekicks Ray Carling and Chris Skelton, turns his attentions to taking on the 'southern nancy' criminal scum in London. But he does not expect to meet DCI Alex Drake (Keeley Hawes), who is battling with her own sense of dislocation.
Ripped from her current world of sexual equality and respect after a shooting, she finds herself faced with the boorish Gene in a two-tone, New Romantic, '80s London with a soundtrack of Adam Ant, Roxy Music and The Human League ringing in her ears. Where is she really from and what does she have to do with Sam Tyler?
Frustrated by each other's stubbornness, the friction between Alex and Gene heats up. However, as the two titans collide, it becomes apparent there is more than just a professional tension emerging.
