Before the party Sophie and her friend, Marshall studied together at Her dorm room together. ( they used to fall in love but now they're just friends). on the evening, Sophie went to a frat party and get home drunk at midnight. When she was just about to sleep, Marshall knock on her door, walking in saying that he left his phone while they were studying. Drunk Sophie let him in but couldn't let her consciousness in her body, so she fainted.
Marshall who realized she was drunk, take her to bed. And just when he was about to leave, Sophie's sleep talk about her dream, make Marshall more curious, and just making a start of a disaster that she will face in the morning.
