Two couples reunite amid the construction of a new neighborhood along the Yangtze River near the old city of Fengjie, which is now under water after the opening of the Three Gorges Dam. After 16 years apart, Han Sanming returns to look for his ex-wife, while Shen Hong has come back in search of her husband who's been away for more than two years. Like the submerged city, the couples must decide what's worth saving and what's best left behind.
