The film takes place in Perth, and begins ten minutes after an Impact event in the North Atlantic, leaving approximately twelve hours until the subsequent global firestorm reaches Western Australia. James and his lover, Zoe, are having sex for the last time at her beach house, where she reveals that she is pregnant with James' child. Wishing to block out all feelings and avoid what's coming, James berates Zoe for sharing her news and leaves for "the party to end all parties".
