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?

With Callum now unwelcome at Boggins' farm and his flat still out of bounds because of a gas leak, Callum turns once more to his oldest, dearest friend, Jordan. And things seem to be going well – Jordan's two dads show Callum some much-needed sympathy and introduce him to the foreign concept of "talking about his feelings." Unfortunately this new-found bond doesn't go down so well with the other member of the house… Jordan.

Meanwhile, Gemma brings home a pet and unwittingly causes Lorcan to relive some very painful memories. Will his emotional constipation cause their romance to founder on the rocks or can he break the cycle of masculine silence and find a way to process his grief?

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?

The three funboys, Callum Brown, Jordan McCafferty and Lorcan Boggin, may have taken the scenic route through emotional development, but they're trying to make the most of life in rural Ballymacnoose.

While working at the local shop, Callum acquires his first-ever female admirer in the form of Gemma, who is new to town and seeking friends. Unfortunately, Callum's burgeoning relationship means that he no longer wants to play video games all weekend with the fellas. This is too much for Jordan to bear and the PSNI are called to restrain him (again).

Despite Jordan's warnings about the devastating dangers of post-nut depression, Callum goes on his first-ever date. And things are going well until he gets an urgent call from Lorcan about a friend in peril: Jordan has jumped off a bridge in the village.

Life is hard, so Callum and Jordan, two emotionally unassembled young lads from Northern Ireland, start the Funboys' Fun Club: a playgroup for childish young men to engage in wholesome mucking about. But when a juice party goes awry, Callum's ultra-religious fiancée Morgan kicks them out, and the Funboys must search for a new HQ. When they come across Marty, a catatonically depressed 60-year-old, can they bring joy back to his life and prove that fun won't necessarily lead to an eternity spent in raging hellfire?
