Phallacy is the story of twelve year old, Bo Williams, who inexplicably wakes up one morning to discover his penis has disappeared. Terrified, Bo confides in his estranged father, Travis (Stephen Graham). A plumber and handy-man by both trade and nature; the epitome of the industrial man, in all his repressed emotional glory. Determined to help his son, Travis promises Bo that he’ll fix it. But in the meantime Bo must keep it a secret. Nobody else can find out. Which is when Travis learns of an incident at Bo’s school. Another student has captured an incriminating video of his son, and unless they pay a bribe, the kid is threatening to release the video online. Outraged, Travis pays a visit to Bo’s school, in a reckless attempt to threaten this kid into silence. But it backfires horribly, forcing Bo to doubt whether he should have ever confided in his Father in the first place.
