When disgraced TV presenter Martin Sharp finds himself standing on top of a tower block on New Yew Eve's can he explain why he wants to jump? The answer's pretty simple: he has, in his own words, 'pissed his life away'. But it seems he's not the only one. Because first single-mum Maureen, then eighteen-year-old Jess and lastly American rock-god JJ turn up and crash Martin's private party. They've stolen his idea but brought their own reasons. Yet it's hard to jump when you've got an audience queuing impatiently behind you. A few heated words and some slices of cold pizza later and these four strangers are suddenly allies. But is their unlikely friendship a good enough reason to carry on living?
