Based on a True Story:

In Australia in 1976, a young girl named Mary (voiced by Bethany Whitmore) is a lonely child looking for a friend. She lives with both her parents but her mother is a chain smoking drunk and a thief and her father, who works in a factory putting the strings on teabags, would rather spend time with his collection of dead birds. Mary remains curious about life and finds the address of an American living in New York. She writes him a letter to become his pen pal. The recipient is Max (Philip Seymour Hoffman), a severely overweight Jewish hypochondriac and full-time no-hoper. Gradually, as they send each other letters, Mary and Max’s relationship develops and we begin to learn more about their past and their heartache and insecurities of being alone.
