After being kicked out of Sheila's by an estate agent, Frank is forced to move back in with his kids, and Debbie couldn't be happier to have her dad back home. Monica, however, isn't happy with the attention Frank is giving his daughter and tells Debbie it's time she found a boyfriend, so Debbie starts dating a Catholic boy called Luke, only for Frank to ruin her new romance and, eventually, his close relationship with his daughter. Meanwhile, Jamie proposes to Karen, who immediately accepts. This causes tension within the Maguire family, especially with Mimi, who sets out to prove that Karen is nothing more than a tart. Bringing Karen along on a robbery job, Mimi lures her into a trap with a security man. But Karen finds an ally in another Maguire child. Elsewhere, Ian begins an affair with the most unlikely of people – the homophobic Mickey Maguire (Ciarán Griffiths). But the affair gets out of control when Mickey falls in love with Ian and risks revealing his sexuality to Paddy.
