Kim sets out into the real world for the first time on a secret mission. But after encountering hapless brothers Nicky and Jay at their local pub, a seemingly harmless prank sets in motion a series of events that sees them all on the run from murderous gangsters.

Kim faces her dad's killer in an epic showdown while Jay tells a disapproving Nicky that he plans to propose to his girlfriend, Beth. As Kim appears battered and bloody from the fight, having learned from Jimmy that the world is not about to end, she confronts Nicky who comes clean with disastrous consequences.

After kidnapping her daughter from Jimmy's, Tina is forced to return to the gangster's mansion with Kim, just in time to save Nicky and Jay from being executed.

Unaware they're now being hunted by Brooks and Thompson on the orders of Jimmy's daughter, the mysterious Terri, Kim finally stands up to her mum.

Before Kim has a moment to cope with the fallout of her mother's deception, Brooks and Thompson's plan to use Jay to track them down backfires.

As the gang reach the safety of the cabin, Kim finds herself back where she started, her plans now shattered and her mum's lies revealed.
