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…

McDull: The Pork of Music is virtually a musical, describing how the kindergarten, now destitute in HK's depressed economy, forms a student chorus to raise operating funds. The choir, of course, becomes wildly famous, and, guided by shady manager Big M (Ronald Cheng), reaches the apotheosis of HK culture: on stage with superstar Andy Lau.

McDull has no black mask or red underwear, and certainly not supernatural powers. One day, an outerspace monster invades the Earth and makes mincemeat of the superhero sent to meet him. Now the responsibility of saving the Earth falls squarely on the shoulders of Mcdull and Risopot. Can they really save our planet? And the outerspace monster, why does he time and again invade the Earth?
