The film is based on the true story of Yoichi Hatta (1886-1942), a civil engineer who traveled to Japanese-ruled Taiwan in 1910 to build a complex irrigation system in the barren southwest. Hatta manages to overcome the initial doubts of local farmers, but a tragic tunnel accident eventually halts the project and shakes his confidence.
Unfortunately the movie Pattenrai!! - Minami no Shima no Mizu Monogatari is not yet available on HBO Max.
