Two lonely misfits embark on a bizarre journey of romance and revenge after bonding at a "come as your favorite animal" costume party in Academy Award nominee Taika Waititi's quirky romantic comedy. Jarrod (Jemaine Clement) is a clerk at the local electronics store. Lily (Loren Horsley) is a shy cashier who earns her keep at the local Meaty Boy. After getting fired from her job, an emboldened Lily determines to put on her favorite shark costume, shed her inhibitions, and attend Jarrod's annual "come as your favorite" animal bash. In the following days a tentative romance begins to develop between Lily and Jarrod, and when Jarrod announces plans to travel back to his hometown and seek revenge on an old nemesis, Lily decides to follow along for the ride.
