This film tells the story of Jiang Xiaoyu (played by Yang Zhigang), Lu Yan (played by Zheng Kai), Zhang Chong (played by He Ziming) and Wu Yun (played by Liu Siyan) who were specially recruited into the Marine Corps. After several years of hard work, they gradually established the belief of "shedding the last drop of blood for the sea of the motherland" and transformed into a new generation of outstanding naval soldiers. It is an inspirational drama. After returning to China, Jiang Xiaoyu formed the Dragon Shark Squadron, and the combat effectiveness of our army increased day by day. In the dangerous mission of fighting against international pirates, the pirates were successfully annihilated and the oath of "shedding the last drop of blood into the sea of the motherland" was fulfilled. The transformation of grassroots fisherman Jiang Xiaoyu from "the king of tricks" to "a great hero" has become a highlight of the film and is worth mentioning. The interpretation of the image of veterans by veterans Liu Xiaoshan, Xiang Yu and others is also real and touching, becoming the "tear gas" of this film. This film is hailed as the "navy version of "Soldier Assault"".
