With Alex, Luke's girlfriend, with all the powers of a normal vampire, Michael with the ability to read minds, Luke being able to change people emotions, Ashton with double the strength of a vampire and Calum able to heal people, things seem normal for the group. But when she finds out her ex-boyfriend, Ross Lynch, is a werewolf things get deadly.
