This is a story of a preserved fish called Mr. Salted Fish who lives at a seafood restaurant on an island and makes a living by working multiple part-time jobs. Due to his unique way of dealing with things, he frequently finds himself in a survival crisis. That's why he takes up a lot of different jobs on the island. In this way, Mr. Salted Fish gets to know the islanders, who are strange at first. But once he learns about their stories, they become friends, and even family. As the annual Fish God Festival approaches, hilarious incidents around Mr. Salted Fish also begin.

We follow Tata in his "what if" stories along with Shaka, his chameleon friend.
