An eccentric documentary filmmaker Declan Desmond offers an inside look at his work chronicling the growth and development of some of Springfield's 'finest' for his documentary, 'Growing up Springfield.' We see Marge put her photojournalism dreams on hold in order to support Homer as he tries out odd jobs in search of success that continually evades him until a strange invention turns it all around for the couple. However, a suspicious Desmond challenges the Simpsons, who have a lot of questions to answer about their overnight success.
