Small town hairdresser Gail Daughtry (Zoey Deutch) is engaged to her devoted high school sweetheart, Tom (Michael Cassidy). Her life takes a turn when a trip to a book signing leads to Tom meeting - and sleeping - with his "celebrity pass". Reeling from the betrayal, Gail impulsively joins her friend Otto (Miles Gutierrez-Riley) on a trip to Los Angeles, where a psychic convinces Gail that the only way to save her marriage is to "even the scales" with her own celebrity pass: Jon Hamm (Jon Hamm). Thus begins an epic journey through Tinseltown as Gail and Otto join forces with a talent agency assistant, a paparazzo, and actor John Slattery (John Slattery), all in the search for Hamm. Along the way, they collide with celebrities and are hunted by a group of Italian assassins as they get ever closer to finding the elusive star.
