Written by David Auburn, “Proof” tells the story of a daughter trying to live beyond an ingrown relationship with her genius father. Catherine (Beth Wittig) has spent years taking care of her genius father, Robert (Christopher Halladay) ,following his mental breakdown. When Hal (Nathan Robinson), a former student, finds a brilliant mathematical proof in Robert’s office, questions arise about the origins of the work. Could the mentally instable Robert have momentarily harnessed the clarity necessary to produce the incredible document, or was it written by Catherine, a self-taught mathematician who left college to care for her father? Amid the search for truth, Catherine finds her most fragile relationships put to the test.
