After Japanese filmmakers were inspired by rumors of the initial breakthrough to make ' Kaiju' movies such as Godzilla and its successors, the creatures were dubbed Kaiju. Mankind first became aware of this world in the wake of World War II, when the use of atomic bombs opened temporary portals between the worlds, to which and through which the creatures were attracted by the radiation fallout, on which they feed. Thule Air Base turns out to hide the gateway to a parallel Earth, in which evolution took a different turn after the early Mesozoic era, resulting in a planet dominated by impossibly immense creatures whose growth is fueled by internal bio- nuclear reactors. Tom offers Jamie a job with his own employer, and Jamie, again out of options, goes in for the interview, is accepted, and is soon on a plane to Thule Air Base in Greenland. Tom has a lucrative position with KPS, a secretive animal rights NGO, and is slated to head out into the field right about the same time Jamie loses the delivery job (füdmüd having been bought out). One delivery client turns out to be Tom Stevens, an old acquaintance, and over the next few weeks of deliveries they renew their friendship. At first rejecting the offer, Jamie is eventually forced to take it after all to make rent, as jobs are scarce in COVID-19-afflicted New York City. Jamie Gray goes to a six-month performance review as an employee for food delivery startup füdmüd expecting to impress boss Rob Sanders with plans to grow the company, only to be terminated and offered a delivery contract instead.
