Season 5 begins with the fallout from the brutal murder of Dexter's (Michael C. Hall) wife. Everyone grieves while trying to understand Dexter's strange reaction to his loss. Instead of matching wits with another serial killer this season, he's fighting his own demons while struggling to accept the responsibilities of fatherhood.

It's hard to follow last season, but the writers have transitioned forward with some interesting leads.
