At the riflery club, Jannis runs into his former schoolmate Marvin, who is hiding from a gang. The two accidentally mix up their backpacks. At the office Christmas party, Jannis finds Marvin‘s pistol. He tries to hide it, unnoticed – above all, he doesn’t want his ex-girlfriend, who is at the party, to see it. But then Marvin shows up at the office and wants his gun back.
Unfortunately the movie Big Red Gun is not yet available on HBO Max.
