Larry Williams and Jean Strange are both released from prison after taking the rap for an oil stock scam while their accomplice, Dan Healy, profited. Larry quickly develops a scheme to recruit British Olympic swimming champion Barbara Hilton and American champion Don Jackson, who are sweethearts, as editors for a revived health and fitness magazine, with Healy as publisher. Along with the purchase of the magazine comes Health Acres, an overgrown resort and ten-acre farm. Barbara and Don soon discover Williams and Healy aim to increase circulation by printing titillating composite photos of women and by taking ads from health quacks. Don counters their efforts by sponsoring an international beauty and health contest, giving his word to contestants that his operation is legitimate. Barbara calls Don home from Europe when she finds Williams and Healy printing torrid sex stories in the magazine and her cousin Sally relishing them. Although Barbara and ethics committee member Reverend Rankin vote to censor the stories, they lose, and circulation triples. Don's moral arguments eventually cause Healy to give him a controlling interest in Health Acres and the money to fix it up in exchange for Don's stock in the magazine. Don and Barbara then refurbish the resort and invite the winners of the contest to perform in the opening pageant and act as health instructors for the guests. Jean makes herself indispensable during the remodelling and Don gives her ten-percent interest in Health Acres. At the opening, Healy and Williams try to taint the resort's reputation by distributing racy pictures of women to the male patrons, while Jean excites the female clientele with photos of handsomely built men. After the pageant, in which the international athletes perform exercises in unison to music, the patrons invite them to parties in their rooms. When Barbara finds Sally dancing in her underwear for a group of drunken guests, she saves Sally by taking her place, and is unable to free herself from lurid demands that she continue to rumba. Two male athletes tell Don about the party and a group of them break it up. Barbara, who has felt threatened by Don's attentions toward Jean, breaks her partnership with him, but he proposes and they kiss. Williams, who sees them kissing gives Jean a call, awakening her, so that she sees Don and Barbara in the moonlight. The next morning, all the guests are dragged out of bed for calisthenics. When Williams and Healy refuse to comply, they call a stock vote and Jean sides with them. Barbara then reveals that Jean's ten-percent was only for the company, not the farm. She drew up the contract with the help of Rankin, who is really from the Department of Justice. Healy, Williams, and Jean are then forced to exercise, while Williams proclaims that he has come upon another great idea.
