The injected woman is a subject in a leaked video that shows the beginning of the zombie outbreak. She is restrained in a white room and injected with a mysterious substance by a person in a protective suit. After the injection, she becomes violently aggressive, attacking the male subject beside her. She bites and kills him by tearing his neck, then continues to eat his flesh. Her transformation demonstrates the infectious nature of the condition, and she later reanimates as a zombie-like creature, spreading the infection.
