Inspired by a true story, "Second Life" follows a woman determined to swim across Taiwan's Sun Moon Lake before she loses her sight completely. She's joined by a group of visually impaired swimmers, all guided by a once-celebrated coach haunted by his past. As they train together, they battle fear, doubt, and old wounds—transforming pain into strength, and strangers into a family. More than a swim, it becomes a journey of healing, redemption, and proving that even in darkness, the human spirit shines brightest.
