Exploring the flooded world of Argo, Kirk and Spock are attacked by a sea creature and wake up transformed into water-breathers by a force no accident could produce. The undersea Aquans who could reverse it distrust surface-dwellers on principle, and only a council member named Rila is willing to help Kirk track down the banned formula — and the venom of a giant sur-snake — before the two officers are stranded in a body that isn't theirs.
