Sarah Zuckerman and Jennifer Jones are best friends in an upscale part of Washington, D.C., in the politically charged 1980s. Sarah is the shy, wary product of an unhappy home: her father abandoned the family to return to his native England; her agoraphobic mother is obsessed with fears of nuclear war. Jenny is an all-American girl who has seemingly perfect parents. With Cold War rhetoric reaching a fever pitch in 1982, the ten-year-old girls write letters to Soviet premier Yuri Andropov asking for peace. But only Jenny's letter receives a response, and Sarah is left behind when her friend accepts the Kremlin's invitation to visit the USSR and becomes an international media sensation.
