Dear Mr. Fidrych centers on 12-year-old poet Marty Jones who wants to be a baseball star. Motivated by the quirky success of Mark ‘The Bird’ Fidrych, Marty writes a poem to the Detroit Tigers pitcher. Fidrych writes back, propelling Marty on a winning streak. Thirty years later, Marty is in a mid-life slump and road-trips in search of The Bird to help Marty reconnect with his family and his youthful optimism.
