Issadora and Lisadora are two identical twins with entirely different behavioural habits. Lisa being the eldest of the twin is rather nerdy and particularly antisocial whiles Issa on the other hand is extremely extroverted and a badass. In spite of their widely different natures, the two are inseparable and love each other dearly. Issadora being her little bitchy and daring self unknowingly messes with the wrong bandits as she tends to witness a robbery that includes a guy from her class, Jordan. With the fear of being busted by the police, Jordan orders for Issadora's immediate death as she has seen their faces but Jordan ends up murdering Lisadora instead since the twin for some reason decides to switch identities that very day. Driven by pain and dreadfulness, Issadora embarks on a journey of vengeance against her sister's murder as she goes undercover and enacts on her little investigation as to who wants her dead and why, which lead to other imminent and rather dumbfounding mysteries being uncovered in the process as she gets entangled in love and vengeance.
