In Ludao in 1982, Su Wanqing, an educated youth, was betrayed by her lover on the night she returned to the city. She resolutely cut off the old relationship and started a career as a translator in a machinery factory with the help of her mother's bilingual dictionary and her own perseverance. She accidentally gets involved in workplace difficulties and entanglements in the past, but in the predicament she meets Military Region Colonel Lu Jinye - a man who has shielded her from the wind and rain many times. He not only accompanies her to find out the truth about her mother Shen Yuwei's false accusation, but also reveals the foreshadowing of the fate between two generations spanning time. From the lonely bravery on a cold night in the cowshed, to the heartbeat under the kite on the beach, to working together to explore the warm past in old photo albums, Su Wanqing realizes her self-growth in the wave of the times, and also strengthens her love with Lu Jinye amidst rumors and protection. When the letters from Hong Kong bring new surprises, the mother's unfinished story is intertwined with the two's future, composing a Ludao love song that hides warmth, courage and a sense of destiny.
