Broke and between jobs, indie musician Izzy (Mackenzie Davis) discovers that her ex-boyfriend, her supposed soul mate, is now engaged to her ex-best friend. Worse yet, she's gone on a bender and woken up in a strange guy's bed all the way across town. To top it off, the loving couple plan to celebrate their engagement at a party this very night.

Enraged and desperate, Izzy attempts to make her way back across town without a car, her quest alternately assisted and hindered by many vibrant and strange Angelenos. With the clock ticking, Izzy is determined to break up those double-crossing love birds before it is permanently too late.
