A synopsis continues: "Set over the week following Mary's death, Cat tries to uncover the truth, looking to the past to understand the present. The audience will constantly question whether Cat is paranoid or has, in fact, discovered a terrible truth about her father. Nothing and no one can be taken at face value. In Blood, the 'truth' depends on who you ask."
