After almost being expelled from a prestigious Chicago music conservatory for a prank gone wrong, twenty-two-year-old pianist Crawford Paul returns home to Northern California for what he predicts will be another boring summer. Concerned his scholarship is now at risk, Crawford accepts the only job he can find: accompanying a glamorous seven-year-old named Isabella to a community swimming pool for lessons. There, Crawford is befriended by a nanny named Nina, an aspiring fashion designer who finds it difficult to hide her disdain for children.
When Crawford meets Armando Leon, a lifeguard and Isabella's swimming instructor, he accepts Armando's offer to help him overcome his fear of water by way of private swimming lessons. As friendship turns into a summer affair, their lust for one another turns to love. When Crawford receives a chance of a lifetime audition, he is torn between returning to Chicago or staying in California to start a new life with Armando. As the end of the summer inches closer, Crawford and Armando fear they will be separated forever.
