The film starring Sul Kyung-gu and Byun Yo-han, is about an exiled Joseon era scholar and a fisherman and their exchange of knowledge in writing a book.

[6] The Book of Fish is a black-and-white historical film set in 1801 about the Joseon era scholar Jeong Yak-jeon [ko] (1758–1816).

In the first year of King Sunjo's reign, Jeong Yak-jeon [ko] is exiled to the remote island of Heuksan due to the Sinyu Persecution.

But when Jeong Yak-jeon learns that Chang-dae's true motivation for studying is solely to achieve success, he is deeply disappointed.

Likewise, Chang-dae realizes that his path is different from Jeong Yak-jeon's and makes up his mind to leave his mentor's side and step out into the wider world.

It was featured in 'Standouts' strand and screened at Lincoln Center and SVA Theatre in the two-week festival held from August 6 to 22, 2021 in New York.

Concluding the review Boram said, "The black-and-white cinematography makes the movie feel like a Joseon Dynasty ink painting, .... and the viewers even get the sense that color is not really important in the script-driven and performance-based piece.
