American fashion model Anne Traymore, swimming off the isle of Majorca, loses a bracelet, which the handsome Manuel del Rio Montoya returns to her. She believes he owns a beautiful yacht called The Swan, but he merely works on it for the wealthy Rene LeClerc.
Unfortunately the movie September Storm is not yet available on HBO Max.
