She fired me, world turns into zombies

Amira, a brilliant pharmacology and biochemistry specialist, single-handedly contains a catastrophic supervirus and saves her employer's company. Her reward is public humiliation at the hands of Diana, the CEO's daughter, who casts her out. Obsessed with fully automated AI drug discovery, Diana forces a rogue algorithm to design "Nirvana," an experimental anti-aging serum. The serum leaves a wave of disfigured victims across the city. Undeterred, she feeds a primordial Antarctic virus into the AI… and unleashes a nightmare no one can contain.
