After confessing his feelings to Evie, Dylan flashes back to an ill-fated weekend in the country with the gang and his hippie girlfriend, Frankie.

Dylan starts seeing Abigail, the hotel clerk from Angus's wedding. Six years earlier, he meets Evie for the first time at a house party.

Dylan looks at a flat with Abigail, and Luke goes to therapy. Three and a half years ago, Angus and Helen are engaged -- and at each other's throats.

At a whiskey tasting, Evie, Dylan and Luke think back on a drunken awards ceremony, where things didn't quite go as planned for any of them.

Dylan meets up with his old girlfriend Emma. In a flashback, Evie and Dylan feel pressured on Valentine's Day, while Luke woos an ex.

Dylan reconnects with Jonesy, a friend who doesn't recall sleeping with him. Three months earlier, the guys try to cheer him up with a wild night out.

The day after Angus's divorce party, Abigail won't answer Dylan's calls. He, Luke and Evie try to piece together what happened the night before.
