Zhao Xun, a modern marine, is caught in a once-in-a-century storm during a naval exercise at sea and swept into a time-space vortex by a massive wave. When he wakes from his coma, the exercise commands are gone from his ears. Instead, the salty sea wind carries the smell of scorched earth and gunpowder. He has somehow transmigrated to the Jiaodong Peninsula in 1942, where war rages everywhere.
Ning Caixia, a kind and resilient fisherwoman, saves him. She has been at home on the waves since childhood, and her character is as hard as a reef and as supple as the tide. At the time, the Japanese army is launching a bloody purge of coastal fishing villages in search of American pilots. Her neighbors and loved ones fall beneath enemy guns, and this sea of blood and hatred ignites Ning Caixia's fury and desire for revenge. With his modern combat skills and practical tactics, Zhao Xun gives the villagers the confidence to fight back. The two join forces against the enemy and work together seamlessly.
They cleverly seize a Japanese patrol boat checkpoint, lure away pursuers to help villagers escape, and set traps on an uninhabited island to strike the Japanese hard. As they return with the surviving villagers, they are joyfully reunited with the Jiaodong guerrilla unit. The Zhao Captain everyone thought had died now stands beside Ning Caixia, who grips a rifle with determination in her eyes.
From then on, the two embark on a hard-fought journey together, from the Huaihai battlefield to the crossing to Hainan, from suppressing bandits in Yunnan to the front lines in Korea. Ning Caixia and Zhao Xun fight side by side, with her feminine resilience shouldering the burden of their mission. This is a tale of devotion to family and country across time and space, and a heroic ode to women awakening and flourishing amid the flames of war.
