Roger and Lance investigate a series of attacks aimed at the Asian community from a group of local schoolboys, including racist graffiti and a pig's head been nailed to the door of their Islamic centre, until the situation spirals out of control and one victim is stabbed during a street robbery. Meanwhile, Steve and Honey arrest a shoplifter who has stolen CDs from her local supermarket, only to discover that the jacket she is wearing links her to a series of jewellery thefts where more than £15,000 of jewellery was stolen. Jack and Jo are on the tail of an out of control Colin, before tracking him down at his friend's garage, where he threatens to burn the place to the ground, with everyone inside.
