Oliver is drugged and kidnapped by a woman named Victoria aka Roulette (guest star STEPH SONG), who tells Oliver that he's involved in a dangerous game and must fight for his life. After Victoria shows up dead and Oliver is arrested by the police, he turns to Chloe for help. Meanwhile, Lois berates Clark for not telling her about Oliver's suicide attempt.

Major Zod and his soldiers release a virus into Metropolis that turns humans into zombies. The only way to stop it is to make an antidote from the blood of another Kryptonian. After Lois is infected, Chloe pleads with Clark to donate his blood to stop the epidemic – even though it risks outing him to Zod.
