They find horses that Robert had blinded, when they had developed defiant pupils and become violent. Jamie and Mitch travel to New Orleans to show their evidence to Senator Vaughn, head of the Environment Committee, but he turns them away because Reiden is too powerful. Afterwards, Gaspard recruits Mitch in a bar and brings them to Japan, where he also rescues Jackson and Abraham from the island.

Jamie hacks into Reiden's database and finds that Butler was blackmailing them to compensate for damages caused by Reiden around the world. Together with Shaffer and Jackson, she finds Leo, who explains Reiden's success is based on the "mother cell," their special vector molecule, which is in all of their products, including human medication, plant herbicides and animal food. However, it has adverse side effects. Leo takes Jamie to retrieve the mother cell, but Shaffer tracks his cell phone GPS signal, and they are intercepted by Hartley. Chloe, Mitch, and Abraham travel to Rio to investigate diurnal bats, which local authorities plan to poison. The bats are attracted by electricity and create a power failure, so the group wants to draw the bats out of the city with a strong electric signal, but are held up by Gustavo Silva and his gang.

In Mobile, Alabama, Jackson notices on a photo that Hartley has the same widened pupils as the rogue animals. Hartley makes an optometrist inject a sample of the mother cell into his eye. Jackson, Jamie and Shaffer go after him but find him dead from the procedure. Shaffer steals the mother cell from Jamie, but Jackson catches him after discovering Ben killed the optometrist.

She wants to find out if Ben had been paid by Reiden so she won't need to hide from police anymore. Mitch examines the captive bear, which apparently fell into hibernation. At first, there are no signs of influence of the mother cell, but when the bear awakens its pupils have widened, and it has developed a thicker skin to deflect needles. Also, the DNA test shows changes with respect to an earlier record. Mitch hypothesizes that the mother cell leads to accelerated evolution, and the mother cell might be able to cure. Chloe, Jean-Michel, Jackson, and Abraham find the missing three bears in an old fortress, where the animals awaken from hibernation and attack.
