Dexter Morgan is a Miami-based blood spatter expert who doesn't just solve murders - he commits them too. In fact, he's a serial killer, but he only kills the guilty, so he feels justified with his lifestyle choices. His policewoman sister and his cop co-workers have no idea Dexter lives a double life; however, adoptive father Harry knows his secret, and does, in fact, help Dexter hone his skills. It's a unique brand of justice for which charming Dexter feels a psychological hunger.
