Emma is still trying to find the murderer of her twin sister Sutton while impersonating Sutton. She highly suspects it was her friends Madelyn, Charlotte, Laurel, and the twins Gabbi and Lili.
While Emma is at a tennis party she sees a picture of Laurel, Charlotte, and Madelyn on the night Sutton was murdered. She is relieved because they are no longer suspects. She knows this because the picture shows them at an overnight sleepover.
It was probably Gabbi and Lili trying to kill me!
Gabbi and Lili are nominated for homecoming queen, and Emma and her friends start to plan a prank to humiliate them. Emma majorly suspects the twins now.
Sutton had a flashback to when she did a prank where she had her car on the tracks and pretended it wouldn't move while a train was coming. This caused Gabbi to have a seizure. Emma finds this out by looking at Gabbi's school medical files. This gave Emma even more reason to believe that the twins wanted to kill her.
While Laurel was trying to get Gabbi and Lili to wear bathing suits instead of dresses as a prank , Emma almost got hit by a huge set light. Emma suspected it was Gabbi or Lili. They deny they had anything to do with it, and they all go to homecoming together.
After homecoming Gabbi, Lili, Laurel, Emma, Charolotte, and Madelyn went on a camping trip. Gabbi pretended to fall off a cliff, and Emma went down to see if she was ok. Gabbi and Lili were there, and they acted like the were going to kill her. Then all of her friends came out and revealed it was a prank. Emma was further away from finding the killer than before.
