Where's The Head?.

Liza, once a notorious mob boss, has always been strategically planning the career of her only son Yan. It is however never in Yan’s intention to follow her mother’s footsteps - instead he aspires to be a filmmaker. As a mob, Yan is highly incompetent, and his disappointing performance already messed up a simple drug deal. Liza desperately tries to save her most sought-after son, but she ends up, along with her son, breaking into her neighbour Mr. Chan's home. They accidentally steal the head of Mrs. Chan, whom they assume was murdered by Mr. Chan. They recklessly decide to blackmail Mr. Chan, and everything goes out of control. Will Liza and her beloved son survive this crisis?
