Amid the heavy artillery fire, war reporter Shen Xinyi and Médecins Sans Frontières Ye Zhao reunited in the Middle East. Five years ago, a sudden kidnapping case occurred on the streets of Paris, and Ye Zhao took a bullet to protect her. Since then, she has become deaf in her left ear, and she has buried her deep love in her heart with her decisive breakup. When they met again, he wore a mask and shuttled through the ruined hospital, while she held up a camera to capture the suffering in the world, but unexpectedly captured his tenderness and guilt hidden behind his professionalism.
When the old telegraph machine made a clicking sound among the ruins, Ye Zhao used Morse code to convey his belated love and marriage vows to Shen Xinyi. In the life-and-death rescue and the undercurrent of pursuit, they are not only comrades fighting side by side against the flames of war, but also lovers trying to untie the knot of the past. From the thrills in the smoke to the secret feelings in the radio waves, this love spanning five years will eventually write the most touching chapter in the romance of Morse code and the perseverance of the doctor's benevolence.
