A group of twentysomething friends are about to discover that life hinges on the smallest twists of fate.

Nathan's heart isn't quite broken but definitely bent out of shape when Fi says they can't be more than friends. Still, he knows it's probably for the best. It doesn't take long for him to turn his attentions towards Rosa, who thinks that Nathan is – literally – a gift from God.

When an angry Rosa tells Nathan that he's given her an STD, he foresees a whole world of trouble — if he's given it to Fi, she could have given it to Jase, and then Jase will know that his best mate's been shagging his girlfriend.

Nathan's got a pocketful of recreational hard-on pills and a date with a prominent porn star – life's looking up... or at least it is until his dad George suddenly arrives to steal both his date and his medication.

Jase is in a coma and it's not at all clear if he's going to pull through – which is why Nathan decides he's got to do whatever it takes to stop Fi finding out what Jase was really up to just before he stepped out in front of the car. If Jase dies, at least she'll have her memories...

As Nathan rushes to tell Fi the truth about Jase's sexuality, there's two versions of events: the one where he tells her. And the whole sadomasochistic love rectangle comes crashing down in several completely unexpected and disastrous ways. Then there's the other, where he doesn't make the bus, but instead gets in a fight with Derek the anal retentive drug dealer and ends up covered in paint. In this version, instead of telling Fi he loves her, he ends up owning a cancerous rabbit called Mrs Snuggles — but does he get the girl?
