'Can I explain why I wanted to jump off the top of a tower block?'

For disgraced TV presenter Martin Sharp the answer's pretty simple: He has, in his own words, 'pissed his life away'. And on New Year's Eve, he's going to end it all.... But not, as it happens, alone. Because first single-mum Maureen, then 18-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?
