Synopsis
Starts out with Ali telling a boy who Hanna is babysitting a story about a girl who killed her twin sister when they were home alone. So I'll just tell you guys the main points about this episode Mona is a nerd, and Noel is very close to Ali. They get invited to a party Aria doesn't wanna go because Ali and Aria witnessed Aria's dad kissing another girl in the car and she has a lot to deal about. Ali threatens to tell Aria's dad about what happened if she doesn't go to the party with Ali and the gang, so she does go to the party and well when they get there you see Jenna who is dressed up exactly like Ali and Ali gets really mad but she offers survival in the social world if Jenna joins the group but she doesn't and that pisses of Ali a lot. So they're at the party and Ali goes missing and texts the girls for help and where to go to help her. They find out the place she is at is a scary, broken down and old house. They go in and there is a person in a scary costume following them in the house and has been watching them. They find Ali hiding saying that there is someone trying to kill her and to get into the room. She locks the door and they try to call the police but get no signal so Ali says she will go into the hallway to get signal and call the police. Ali then says to lock the door and don't let anyone in but her. She then gets attacked by the guy or girl that has been following them in the scary costume. They try to get to her but the door is jammed and won't open so she kicks the scary costume person in the stomach and runs so the girls go out through the window and get back in the house and see that Ali is sitting on an old rocking chair and saying that it was just a trick and the guy in the scary costume was Noel. They all think that Ali has gone too far and they thought she was gonna die but she says they passed a test and she knows she can count on them. They go back to the party to find that Noel was not the one that was attacking Ali and scaring the girls and that the person in the scary costume was someone who was really trying to kill Ali. then Lucas who is also in the same scary costume comes behind Ali and calls her a bitch. But there are a lot of people at the party that is wearing the same scary costume so we see the person that tried to kill Ali take off his or hers mask and we don't see the face Ali then gets a text from the one and only A.
