While their parents continue an endless legal battle over their divorce, Jeanie and her brother Tommy spend Four-Twenty indulging in self-destructive habits... and scheming to murder their father. Joined by their hip grandmother, their pediatrician, a musical theatre ingénue, and Jeanie's long-term boyfriend, the siblings take a wild trip exploring the lows and highs of marriage. A refined stoner comedy, JOINT CUSTODY is a play about divorce, dreams, and illegal drugs.
