Only loosely tethered to shore but never ready to set sail, Col, Baxter and Jackie have made a jumble of boats in a Fremantle marina their barely floating homes. It's Australia Day, and as the city noisily celebrates around them, they just want to hole up and be left in peace. When Dee, a young English backpacker, stumbles upon them with far too much anger and alcohol in her belly, she well and truly rocks their boats, and the past they want to escape from gets dragged up like jetsam from the sea.
