PJ finds himself at loggerheads with Jo over her sympathy for a woman on work release from prison. The arrival in town of her son and defacto husband leads PJ to suspect that the woman is still involved in their criminal activities. His views seem to be confirmed when she escapes from prison, but Jo discovers she has a different motivation, and together she and PJ must try to save her son's life. After agreeing to be 'just good friend' PJ naturally assumes Jo will now be moving out of his house, but Jo has different ideas.
