Conor and Jock have been instructed to take up unpaid part-time work experience at Mairead's side on the fish stall in the English Market, bringing them up close and personal with life in the real world. With Jock's extra mouth to feed in the McSweeney household, money is getting more and more tight, leaving the trio to come up with inventive and unsatisfying ways of making food last longer.

Determined to help out Mairead financially, the lads start to think about ways they can come up with some extra cash. The freak local catch of a very expensive fish gives the two lads an idea, leading them on a dubious adventure involving breaking and entering, a hilarious struggle and a memorable trip through Cork with their ill-gotten gains.

Meanwhile, Mairead and Sergeant Healy are in two minds about taking their friendship to the next level while Maired tries to give Healy some driving lessons.
