In Providence, Rhode Island, two inept, struggling musicians, Sam and Eddie, are mistakenly identified as expert safecrackers by an incompetent gang member. This mix-up catapults the hapless duo into the world of organized crime under the intimidating leadership of Big Fat Bernie Gayle. Bernie is convinced they are the best in the business and gives them a daunting ultimatum: crack a series of safes or suffer severe consequences. Terrified and out of their depth, Sam and Eddie bumble through their first job, relying on surprising improvisation and sheer luck to avoid detection. They gradually become entrenched in this new life, trying to bluff their way through increasingly difficult situations while attempting to maintain their innocence.

Meanwhile, their antics catch the attention of Leo, a seasoned safecracker who feels his territory is being threatened by this unexpected competition. As the pressure mounts from both Bernie and Leo, Sam and Eddie's friendship is tested, with each heist forcing them to think on their feet and navigate the chaotic underworld where they don't belong. Along the way, they encounter an array of quirky characters, including an eccentric dance troupe leader whose paths intertwine with theirs in unexpected ways. As their bumbling bravado grows, Sam, Eddie, and the colorful cast around them weave through a chaotic comedy of errors that draws them deeper into a heist-filled misadventure beyond their original intentions.
