Don and his boss Jason socialise together for the first time in the form of a double date with two posh girls they met at work. Don learns never to judge a book by its cover, as his date Felicity is far from prudish. Everything seems to be going well until Felicity invites them to her parents' country house for the weekend. It's a world away from Don's life and he struggles to fit in. He also has some over-protective parents to contend with.
