When Jamie makes a food delivery to an old acquaintance, he's pulled into what he's told is an "animal rights organization," though the animals are not from our Earth. Now part of the Kaiju Preservation Society, Jamie discovers the dinosaur-like creatures that roam an alternate, human-free dimension of Earth. Jamie is then paired with a kaiju named "Frontrunner" and starts to have a "Best Friend" friendship with him. But then an enemy of the Kaiju Preservation Society named the Teammates Of Death comes to capture some Kaiju to mind control and use to destroy Earth. It is now up to Jamie, Frontrunner, & some other Humans & their Kaiju partners to stop the invading evil in it's tracks before it is too late. (The events of this story take place before the events of the first installment in the Apex Guardians saga.)
