Clarinda, the daughter of a diplomat, seeks revenge for her best friend Nina, who fell from a building and lies in a coma. She transfers to an elite high school carrying a suicide note bearing three names: Sabrina, Janis and Betsy. Using lavish gifts as bait, she successfully approaches the vain Betsy and follows the clues to infiltrate their private party. At the party, the gang leader Sabrina eyes her with hostile coldness. Meanwhile, Knox — a hotheaded expelled student who once claimed he would do anything for the trio — secretly locks all exits, cutting off Clarinda’s escape route. All the villains have gathered. Trapped in an enclosed predicament, Clarinda initiates her revenge. But is she the hunter holding all the strings, or the next victim walking straight into a deadly trap?
