Jack Flex, a penniless, muscle-bound "creative genius" who maniacally pursues his dream of appearing on his mother's favorite home shopping channel to sell the Heavy Hat — an obviously dangerous fitness gadget that supposedly "increases the flow of Hope Molecules to the brain." When Jack convinces a desperate network staffer to give him his big break, there's just one problem: his pitch is filled with lies about being a Hollywood trainer who has celebrity endorsements. With only one week to fulfill his promises before his chance at success vanishes, Jack careens through Los Angeles in an increasingly frantic quest to prove himself.
