Queena DeLany as Claire, Kyle Handziak as Hal, Dakota Dieter as Catherine

Catherine is a young woman with a lot to prove—to her lover, her sister, her departed father, and especially to herself. 

 Was she a good daughter? Has she inherited her father’s math genius or his madness—or both?  Has she made math history, or is she as deluded as he was? 

 Is her sister right about her—that she needs to be taken care of?

 Why doesn’t her new boyfriend believe her? Has she followed her heart into the wrong relationship? 

What does it mean if they won't believe her or trust her--without proof?

 Proof is a mystery, a love story and a family drama with humor, emotion and intelligence.
