A new trailer for episode 13 shows animals going wild and turning on humans too. With the cure lost in the plane crash in episode 12, Jackson and his team try to find a way to stop the animals.

The promo opens with Jackson, who looks injured and bleeding, saying, "47 people lost their lives in the crash, along with the cure." The video voice-over declares, "Animals have unleashed their wrath on the world; now the final battle begins."

"The animals have stopped feeding on each other, they just seem to be feeding on us," claims another member of the team who is entrusted with the job of stopping the apocalypse. Based on the bestselling novel by James Patterson, Zoo is a global thriller about a wave of violent animal attacks against humans sweeping the planet.
