As a child, Bobby Mak was known as Mcdull. Although Mcdull wasn‘t the sharpest tool in the shed, his mother was a different story. Her astounding intelligence and resourcefulness enabled her to, for example, simultaneously run more than six businesses from a space of less than 100 square feet. Mcdull and his mother lived together happily during Mcdull‘s childhood, but things began to change as Mcdull got older. A distance that never existed before began to grow between him and his mother…

As the 18th descendant of an extremely insignificant philosopher and inventor from ancient China, McDull is fortunate that he does not have a lot to live up to. However, his mother has higher aspirations for him and decides to send him to a martial arts school in China. Overweight and slow on his feet, McDull is the last of his classmates to run away when the headmaster needs to choose someone to represent the school in an international children's martial arts competition.
