After a gas leak at his flat, Callum moves in with Lorcan and his dad, Sammy, aka the biggest git in Ballymacnoose. Driven by a desire to no longer be a pushover, and in a desperate attempt to get over his break-up with Gemma, Callum goes under Sammy's wing and unleashes his own inner git.

Meanwhile, Jordan's two dads are finally tying the knot, and Jordan is caught up in all the excitement of the wedding. But whilst Jordan's attention is focused on suit fittings and stag dos, will Callum's transition to full baddie cause an irreparable breakdown in the funboys' friendship? And will there be any other disastrous consequences to Callum's personality transplant?

Gemma and Lorcan throw a party at Boggins' farm and it's the biggest social event in Ballymacnoose with a whole eight people attending. One of those attendees is Gemma's brother, David, who is tall, cool and very emotionally articulate. And weirdest of all, he seems genuinely interested in being friends with Callum. Has Callum finally found someone he can be himself with, who he can let his guard down with and who won't take advantage of him?

Meanwhile, Gemma finds one of her old personality quirks coming to the fore again as she struggles to maintain her identity amidst the intoxicating brew of Lorcan's old-fashioned country charm. Will Lorcan pick up on his lover's signals or barrel on as normal like a dumb pig?

And while Callum focuses on his new friendship with David, Jordan decides to branch out himself and become mates with Frank. But can he handle Frank's famously toxic banter?
