Angel Baby is a tragi-comedy of love, loss, and mental illness. Protagonists Kate and Harry are outpatients at a psychiatric clinic: Kate believes that her guardian angel, Astral, is sending her messages through the television game show Wheel of Fortune and Harry is schizophrenic. After they meet and fall in love, Kate and Harry move away from their carers and attempt to face their adversities together. However, their new-found independence begins to draw them into an intense and emotion-driven world of their own. Over-confidence eventually leads to them stopping their medication, which is when the real struggle begins.
