In 1937, the war broke out. Lu Xiaoqi, a rickshaw driver on the beach, was eking out an ignoble existence in the troubled times, but due to an accident, he was involved in the bloody whirlpool. From a street ruffian to a Japanese military driver, he put on the "Night Owl" mask between the enemy and ourselves, and wandered in the abyss of conspiracy and betrayal. In the past, brothers turned against each other, and misunderstandings between beauties gradually deepened. Only a copper coin hid the unburned spark. When faith is tempered in lies and the truth is silenced in the smoke of gunpowder, can the lonely night owl tear through the darkness? In the bloody age, the names that no one knows will eventually ask for the echo of history.
