Blonde bombshell Jayne Mansfield stars in this titillating romp about two married women who will stop at nothing to get pregnant. After embarking on a cruise in hopes it'll relax her overstressed husband, Sandy (Mansfield) meets Claire, who hits the high seas with the same intent as Sandy: to get knocked up. During an alcohol-fueled evening, the couples swap mates, resulting in hilarious complications when both women discover they're pregnant.
