Beach volleyball rising star Lucas enters school determined to win the captaincy and a scholarship—only to clash with the overwhelmingly talented Alex. On the court, they're bitter rivals. Then fate plays a joke: the two sworn enemies become stepbrothers in a blended family. Under one roof, tension turns into something more—Alex taunts him openly, yet his eyes always follow Lucas, his feelings unmistakable.
