Talented pro beach volleyball player Carmen Lopez has always stepped back for her twin sister Sylvia before the world championship. Driven by bitter envy, Sylvia laced Carmen’s sports drink with harmful drugs the night before the key match, ruining her knees and ending her athletic dream. While Carmen endured painful knee surgeries, Sylvia teamed up with their rival and won the championship. Having surveillance proof of the poisoning, Carmen spent three years on tough rehab and worked as a volleyball commentator to study Sylvia’s weaknesses. She accepted Sylvia’s plea to team up as a revenge trap. After winning tournament matches, Carmen handed over evidence, getting Sylvia banned. Fully recovered, Carmen partnered with rookie Anna and claimed an Olympic bronze medal.
