After Luke and Larry Wimms move across the country to start a new life, things quickly get out of hand when Larry decides to take the place of an international hitman they find dead at their hotel. Larry is a social goof and is notorious for inappropriate comments, cheesy "Dad Jokes," and excessive air quotes, so Luke isn't sure how his dad is going to pull this off.
To make the situation even worse, the dead hitman works for a world-renowned secret assassin organization led by a creepy old lady who lives in the shadows. But after a few lucky breaks on Larry's first mission for the organization, the creepy old lady, and Larry himself, are convinced that he is one of the best hitmen in recent history. Luke knows better and tries to push his dad back to the good side of the law- until the cash payments from the creepy old lady for each hit make doing so a little harder.
Accidental poisoning, accidental explosions, and poorly executed hand-to-hand combat finally convince Luke and Larry to take their earnings and run before the creepy old lady and her real assassins figure out who they are. Now the only question they need to answer is: what do we do with the dead hitman in the freezer?
