A love story about two people who appear to be utterly wrong for each other, but may be entirely right, begins.

Seamus and Janet meet in Belfast and, after a glorious night of laughter and sexual tension, Janet makes a shocking suggestion.

Seamus' girlfriend whisks him away for the night and drags Janet along, too. An agonising night of lies and subterfuge ensues.

At last, the day has come: the affair is on! But when they realise they've both 'caught feelings', things take a different turn.

It's over between Janet and Seamus, but Janet's boss urges her not to give up. Can they find a way back to each other?
