Vinnie has been hiding out in his weed shed since faking his own death to escape from local gangster Terrance McCann. Tommo and Erin need his help and try to lure him out of hiding with a new business proposition and together with the lads they plot to rob a travelling circus. With the help of a disgruntled clown, Mr Popov, the gang aim to make this theft a 'roaring' success.
Vinnie agrees to grow weed on an industrial scale for McCann and the lads get busy setting up a new grow shed. Meanwhile, Erin attends a disastrous dinner party with Jake's family and Tommo hatches a plan to steal some erotic furniture to re-vamp the Rat & Cutter. But what starts as a simple robbery quickly descends into bedlam when a rival gang of thieves turn up and the lads find themselves joining an elaborate treasure hunt.
