Ryder, a top swimmer, rivals his stepbrother Lucas for his mother's love. Newcomer Tristan steals Ryder's captain spot—and his focus. Ryder despises him. One reckless mistake: he accidentally sends a solo explicit clip to Tristan, then retracts it, sure Tristan won't open it. But Tristan starts acting strange. Ryder later finds the clip saved in Tristan's phone—watched over and over.
