Walt (Shameik Moore) is an unemployed underachiever who discovers a newfound talent for bowling. Encouraged by a barfly named Skunk (D'Arcy Carden), he launches a pro career to save the local bowling alley from foreclosure. With his powerful rolling skills and unconventional style, Walt becomes an unlikely bowling hero - much to the chagrin of legendary champion Linda "The Crusher" Curson (Susan Sarandon).
