A down and out guy called Ping gets a job at a convenience store one night. Ping decides to have some fun to strike back against his new unpleasant employer, Fat Boss, and colleague Mabel joins in the mischief. During the night, a passerby needs the toilet, a young woman in a cheerleader's outfit wants some condoms, and Grandpa wants a sandwich and some large scissors. Before long, insanity ensues and the Exceed convenience store becomes the scene of a robbery.
