Blue Heart consists of two related short plays, one about a father and daughter, the other about a mother and son. In Heart's Desire, a father, mother and aunt are waiting for a woman to arrive home after years in Australia. In Blue Kettle a middle-aged man and his girlfriend are involved in a con trick, making elderly women believe they are the man's long-lost mother. But neither play is what it seems. Something catastrophic is happening which disrupts and destroys them.
