橋頭青年李文欽以行動追求民主自由，而他刻骨銘心的愛情故事和摯友間的兄弟情誼，交織構築了台灣1970年代的革命青春。

「盐水大饭店」由导演郑文堂、林志儒共同执导，取材自台湾农运先驱戴振耀的年少时代，描述男主角李文钦在追求民主自由过程，拥有一群患难与共的挚友与刻骨铭心的爱恋，用眼泪和热血构筑1970年代的台湾式革命青春。

The Qiaotou youth LI Wen-hsin was arrested during the December 10, 1979, demonstration spearheaded by Formosa Magazine. After being thrown into prison, he learned a way to survive: mixing saltwater with white rice. He also recalled wonderful times with his girlfriend A-chun, the joys and suffering he shared with friends and family, and his longing for democracy. In this prison, referred to by inmates as the “Hotel Saltwater,” Wen-hsin and his companions, though suffering greatly, never let their thirst for freedom be extinguished.
