When May, an OCD nurse with a compulsive swearing problem, goes to Los Angeles to retrieve bone marrow for a critical transplant, she runs straight into the past she has been hiding from. Flustered, May loses the cooler and must enlist the help of the one person she had hoped never to see again; the man she abandoned four years ago. With less than 24 hours to find the cooler, they embark on a journey through the streets of Los Angeles. Past and present collide, the closer they get, the closer they come to finding the truth of what went so terribly wrong between them.
