It's the big opening night for All Steve's Pals, with Dale determined to make it the best launch ever and show Rachel he's the kind of serious safe bet she can spend her future with. Rachel's work has thrown up a different future for her and she's forced to choose between Dale and a dream job in Sierra Leone. Meanwhile Ken, now fired from work, is a man on a mission - with one last roll of the dice to get his job back.
When Ken and Lorna collect their daughter Rachel from the airport, they're horrified to learn that she's returned from her gap year with more than just a henna tattoo and braids in her hair.
At the arrival gate, she promptly introduces them to her new husband, Cuckoo - the squared-jawed, self-appointed "spiritual ninja" who is now their son-in-law. Cuckoo is every parent's worst nightmare - a slacker full of outlandish, New Age ideas.
Ken and Lorna have no choice but to welcome him into their family home - and if every Englishman's home is his castle, then this hippie has stormed Ken's fortress and plundered everything, most unforgivably, his princess.
