PJ's quest to solve the mystery of Maggie's murder leads him to the bass guitarist in a recently re-formed rock band. When the muso refuses to give him the answers he wants, PJ decides to apply the pressure by applying for a warrant to search for drugs. Heroin is found, but PJ's plans are soon thwarted because the leader of the band, a faded rock star, takes responsibility for the drugs. Meanwhile, Jack strikes up a friendship with the band's spunky back-up vocalist, who turns out to be the daughter of the band's promoter, Bryce McLeod. PJ investigates Bryce and discovers he was not only named in a top secret drug trafficking inquiry, but was also a close friend of Barry Craig's. Perhaps this is the missing link he is looking for. With PJ applying pressure on Bryce he pulls the plug on the band, bringing about tragic consequences for one of its members. When Jack rescues the daughter from a drug overdose she realises the truth about her father, and decides to help PJ.
