The Heelers are baffled when a man confesses to murdering a young woman, but they can't find her body. Bridie flirts with Jonesy, causing escalating aggression from the boyfriend, who takes it out on Bridie, then staggers into the hospital with a stab wound. Meanwhile the young woman is found, but says she's been raped. When the Heelers go to question the boyfriend and the young woman, they discover both have disappeared from the hospital—along with Jonesy, who was supposed to be guarding them. And then an hysterical Bridie leads them to her boyfriend's bloody dead body.
