In Moonlight, Alex O'Loughlin plays Mick St. John -- a vampire that spends his eternity protecting the living. It was either protect them or eat them... he chose to go against the norm after saving a young girl's life. But wait -- he runs into the girl again and their bond is unshakable. She's an investigative reporter now, and he has to hold his feelings for her at bay (because of, ya know... the whole bloodsucking thing.) Now she's had to save his life by letting him sink his teeth into her and things are just AW-kward!
