Chicago, sometime. Two people meet in the armory of the Art Institute by chance. Prior to their encounter, he is a doctoral student who manages his destructive thoughts with compulsive calculations about time travel; she is a bipolar counterfeit artist undergoing court-ordered psychotherapy. After their meeting, those things do not change.Everything else, however, is slightly different.Both obsessive, eccentric personalities, Aldo Damiani and Charlotte Regan struggle to be without each other from the moment they meet. The truth - that he is a clinically depressed, anti-social theoretician and she is a manipulative liar with a history of self-sabotage - means the deeper they fall in love, the more troubling their reliance on each other becomes.
