The film takes place from 1976 to 1998 and tells the story of the unlikely pen-pal friendship that lasts for 22 years between Mary, a chubby lonely 8-year-old girl who lives in Mount Waverley, a suburb of Melbourne, Australia, and Max, a 44-year-old, severely obese, secular Jew atheist with Asperger syndrome who lives in New York City.
