Three couples live the 1960s high life in ACAPULCO A GO-GO. The location is Tequila A Go-Go, a dance club for vacationers with money to burn and time to waste. Celia is married to Mario, an architect who is living in Mexico hoping the warm climate will improve his health. Elizabeth is an American heiress who has hooked up with local sailor Jorge, who is only too happy to spend her money. Meanwhile, Elizabeth's younger brother Robert romances a go-go dancer named Rita. Picturesque local scenery is the backdrop for these three giddy liaisons.
