Dan and Brenda Stevens finally planned a night out without the kids, and were able to find a babysitter at the last minute. Brenda's friend Karen's daughter Susan happened to be free for the evening because her boyfriend was sick, so instead of being stuck home all night with nothing to do her mother suggested she babysit her friend Brenda's kids, and make a little extra money. Susan was happy to earn some easy money for a couple hours.

Susan got ready, and said goodbye to her mother, and drove on to the Steven's house for what she thought would a quiet night, and some easy babysitting money. Instead, it was going to be a night of terror.
