Welcome to The Islands, a place that invites new friends to call it home. No one intends to come here; apart from a powerful tuna conglomerate, no one on Earth knows the place exists. However, castaways often arrive during significant life events, typically through what seems like magic teleportation, by tripping over their shoelaces or, more commonly, a few centuries ago, due to a shipwreck. Once they arrive, they embark on a journey to uncover the Islands' purpose for them.

That is, until one day, a visitor who wasn't part of The Islands' plan arrives: Merk, an 11-year-old boy with a severe case of main character syndrome. After tinkering with some equipment during a field trip to the Tin & Fin Company, he accidentally finds himself stranded on the shores of The Islands.

Now, Merk faces the challenge of returning home and vlogs the entire experience after retrofitting the Tin & Fin equipment to establish the first internet connection from The Islands to Earth. Along the way, he shares the stories of the castaways he encounters, whether they've been there for hundreds of years or are fresh catches who just arrived a few hours ago.

What Merk doesn't expect is to become central to saving The Islands and its inhabitants from the evil plans of the Tin & Fin Company. Will Merk learn to be selfless and help his new friends, or will his desire to go home prevail?
