Cocoon (1985)

Beneath the shimmering surface of an unassuming pool lies an extraordinary secret. A clandestine dip transforms a band of trespassing seniors, each yearning for days gone by. Immersed in waters harboring alien cocoons, they experience an unforeseen metamorphosis. The years begin to peel away, replaced by a surge of youthful vitality that defies explanation. As their bodies rediscover forgotten strength, they confront the exhilarating, and potentially perilous, implications of their newfound vigor. Can they control this borrowed time, or will its source claim them in the end? This is where their journey truly takes hold.
