Erica toughens things up in Wentworth, aided by a gleeful Joan, who insists on enforcing the most petty rules. Meg is appalled, and falls out with Colleen when she supports it. Bea drops hints to Meg that Margo started the fire, and she in turn asks Erica to reopen the investigation. Erica refuses, and instead chooses to transfer Margo out of Wentworth to get rid of her. Erica introduces a silly points scheme thing where the women get points for being good, and get points taken off for being bad. If they want privileges, they need to earn them. The women think it stinks, so does Meg, and Joan takes great delight in totally abusing the scheme. The women suspect Jean is hiding something. Hazel is arrested for passing the stolen money, and set up by the cops to make it look like she confessed to the bank job in WA. Back at Driscoll, Judy's estranged sister Frances unexpectedly turns up from America.
