New W.P.C. Rosie Fox is partnered with P.C. Eddie Santini to investigate when the body of a junkie is washed up on the banks of the Thames. Santini and Fox argue over their cases, and it seems their working relationship will not be a smooth one. Santini reckons graduate Fox will not be able to handle the pressure when she goes undercover as a prostitute in a CID operation, then nearly ruins the operation when he finds himself attracted to her. Celebrating a successful arrest, the two share a drunken snog back at the station, but moments later Santini forces himself on Fox in the locker room, leaving her confused and frightened.
