When nurse Eliza Hamilton is mugged on her way home from work late one evening, the mysterious Roman Holbrook appears out of the darkness and fights off her strange attacker. He quickly disappears into the night before the police arrive, leaving a semi-conscious Eliza questioning if he was, in fact, a figment of her imagination.

That is until he shows up on her doorstep one rainy night – and all hell breaks loose again.

But is this man her hero or does he have a more sinister motive for wanting her kept alive?
