Proof at El Portal Theatre

In PROOF, Catherine has inherited her late fathers mathematical brilliance, but she is haunted by the fear that she might also share his debilitating mental illness. Caught between a new-found connection with Hal, one of her fathers former students, and the reappearance of her sister, Claire, Catherine finds both her world and her mind growing increasingly unstable. Then Hal discovers a groundbreaking proof among the notebooks Catherines father left behind, and Catherine is forced to further question how much of her fathers genius or madness will she inherit.
