One afternoon, Abi Morgan returned home to find her longtime partner and father to their two kids collapsed on the bathroom floor. Jacob, who had been undergoing treatment for multiple sclerosis, had suddenly experienced a series of seizures and had to be put into a medically induced coma. As he slowly regained consciousness after six months, he made tentative steps to communicate with those around him, and grappled with the host of issues that had been triggered by the damage caused to his brain. But while Jacob recognized his family and friends, he didn't believe that the Abi standing in front of him--who had sat by his hospital bed, juggled care of their children, and liaised with his slew of doctors as he slipped between life and death--was in fact his Abi. Instead, he saw a woman whom he believed to be an imposter.
