The action takes place in the Gents and Ladies loos of a tacky Liverpool club, Bransky's, where Dave and Linda (bride and groom-to-be) have decided, unbeknownst to each other, to hold their stag and hen parties.
Linda runs into her old boyfriend, Peter, a musician with a single climbing up the pop charts, but who is back in Liverpool on this particular night - playing a gig at Branskys.
Whilst entering the club, Dave, in a drunken stupor, becomes ill from the indian curry he ate (washed down with a copious mix of cider and Guiness) and spends the remainder of the evening (and the play) in the Gents, with his head down the lavatory bowl!
His mates, including Kas, and gang leader Eddie decide to take the law into their own hands when they suspect that Linda has developed a crush on Peter and may be having second thoughts about marrying Dave.
Warning: This play contains strong language and adult themes.
