Based on the award-winning stage play, "My Left Nut" is a three-part coming of age comedy drama about friendship, family, grief and testicles. The series follows school-boy Mick and his journey after discovering a swelling on his testicle. He can't tell his dad; he died seven years ago. He can't tell his mum Patricia; she's got a million other things on her plate. He can't tell his schoolmates; there's an upside to rumours about the bulge in your trousers… And it’s not like it’s going to complicate things between Mick and his first girlfriend anyway, right?
Teenager Mick discovers a swelling on his testicle. Not sure what to do, he attempts to hide it before it can get in the way of his first proper date with Rachael.
Mick’s plan to hide his swelling backfires and he’s horrified to find the whole school talking about the bulge in his trousers. Rachael thinks Mick is spreading rumours about her.
Mick goes full throttle at Tommy’s house party as he tries to forget about his testicle. But things start to go wrong when he attempts to lose his virginity.
