Keeping with Commitment

 The play focuses on Catherine, the daughter of Robert, a mathematical genius in his fifties and professor at the University of Chicago and her struggle with mathematical genius and mental illness. Catherine had cared for her father through a lengthy mental illness. 

His ex-graduate student Hal discovers a paradigm-shifting proof about prime numbers in Robert's office. The title refers both to that proof and to the play's central question: Can Catherine prove the proof's authorship? 

Along with demonstrating the proof's authenticity, Catherine also finds herself in a relationship with Hal. Throughout, the play explores Catherine's fear of following in her father's footsteps, both mathematically and mentally and her desperate attempts to stay in control.
