In Cold War-era West Berlin, American Coca-Cola executive C.R. 'Mac' MacNamara is tasked with playing babysitter to his boss' spoiled 17-year-old daughter Scarlett, who proves more difficult than anticipated when she reveals that she is pregnant by a Communist.
An eccentric marketing guru visits a Coca-Cola subsidiary in Australia to try and increase market penetration. He finds zero penetration in a valley owned by an old man who makes his own soft drinks, and visits the valley to see why. After "the Kid's" persistence is tested he's given a tour of the man's plant, and they begin talking of a joint venture. Things get more complicated when the Coca-Cola man begins falling in love with his temporary secretary, who seems to have connections to the valley.
