Having her handbag stolen proves to be a blessing for Fiona when a handsome stranger named Steve comes to her rescue. Lip is shocked to discover Ian could be gay and decides his brother should pay a visit to the ever-accommodating Karen Jackson down the block. But the sudden arrival of her furious father Eddie ensures Ian's already-slim chances of happiness with Karen take a severe blow. Meanwhile, Steve buys Fiona a romantic gift, but for some reason she's less than impressed with it.
Drunk as a skunk, Frank has a run-in with Karen's father and returns home to take it out on Ian. The next day is Friday, and Frank is nowhere to be found, which is a bit odd since he never misses disability check day. The family starts a manhunt. .
Having blown off Steve, Fiona turns her attention to Tony, the cop who's had a crush on her since childhood. Steve, however, has not given up the fight. Elsewhere, a woman from the Office of the Inspector General suspects that someone may be stealing and cashing social security checks belonging to Aunt Ginger, the Gallagher's elderly aunt, who owns the house they live in.
Debbie, sad and lonely after Aunt Ginger leaves, steals a little boy from a birthday party. In classic Gallagher style, the family hatches a plan to return the toddler safe and sound without attracting attention from the Chicago Police Department, which makes the kidnapping a top priority.
