A boy climbs an unsteady path to adulthood under difficult circumstances in this drama from Australia. Shaun (Kane McNay) is a teenager growing up in a run-down suburb of Melbourne. His father Sam (Brett Swain) is in prison, while his mother Jenny (Nell Feeney) is too lost in her problems with alcohol to provide much guidance for her children. Left to his own devices, Shaun commits petty theft, smokes pot, and deals drugs to his friends as they hang out at the nearby shopping mall. Shaun seems unable to reach out to anyone, not even his girlfriend (Lauren Hawker) or Darren (Brett Tucker), a social worker eager to help him. When his father is released from prison and brings his mistress to the "Welcome Home" party Jenny throws for him, Shaun comes to realize that if he is ever to resolve his problems, he will have to do it without the help of his family. Mallboy marked the feature film debut for writer/director Vincent Giarrusso.

The seasons go by her window, she dreams about a boy she knew; his baby brother is now a man. A film about time, depression and a woman's need for a story.
