It was Frank's birthday - an excuse for three couples to have a night away. Caught between caring for their children and worrying about their parents, they were ready to have a good time. The drink flowed, Dublin felt a long way away and when Frank proposed they swap partners for the night, they forgot they were stressed about their finances and exhausted by their responsibilities.

No falling in love. But life doesn't follow the rules.
