How to survive that pivotal moment when admiration turns to attraction?

Hélène Dupont, a scientific translator in Brussels, Belgium, cherishes two things: flowers and her cat. She writes bad poetry to help her survive her painful existence with her husband, until she is forced to undergo a radical lifestyle change. Sylvie Routard, a young Greek photographer, enters Hélène's world as her new private swim coach. During their daily lessons, Hélène's admiration toward Sylvie turns to attraction. As unsettling feelings hijack Hélène's mind and body, daydreams featuring Sylvie enter her world—even her poems. While the two athletes increasingly feel underwater vibes in the pool, Hélène questions her relationship at home, and everything else in life.
