Ben has joined the Salvation Army, much to the amusement of his colleagues. They are certain it's only because he fancies the new captain, Marissa, but Ben denies it. He sets out to impress her but his courting attempts are thwarted when an investigation keeps leading to some of her favourite welfare recipients. When a young boy's guinea pig goes missing, Ben sees it as an opportunity to show Marissa his softer side. He ropes Jonesy into helping. Eventually, their hunt leads to the missing pet—and also the shoplifters. But will Ben's efforts be enough to convince Marissa to go on a date with him?
