Gilligan's Island (1964)

S03E14 All About Eva

A dowdy, unassuming woman arrives on the island in search of solitude. The girls decide to give her a glamorous makeover to boost her confidence, transforming her to resemble Ginger's doppelgänger. While the castaways hope this new look will inspire her to return to society—especially since she has a boat with a hidden key—she ultimately chooses to leave them behind and heads back to Hollywood, eager to chase after Ginger Grant's film career.
