At 52, Oh Ran-Hui decides to take up swimming again to shake off her loneliness. But even before she steps into the pool, she’s thrown off balance by the “shower room rules,” and soon finds herself swept up in the “cliquey behavior” of the regular members…!

A hyper-realistic, humanistic drama featuring middle-aged women whose intensity rivals the currents of the pool!
