Emma's best friend is a cop. They've known each other since high school and have kinda always had a thing for each other.
So, there are a string of murders that have happened in her neighborhood and Emma is scared for her life. She calls her friend and asks if he can watch over her until they find the guy. So, he shows up in a different car and no uniform so he can be undercover and keep her safer. A storm breaks out and the power goes out...that's when things get interesting between the two.
