An eccentric documentary filmmaker Declan Desmond (guest voice Eric Idle) offers an inside look at his work chronicling the growth and development of some of Springfields finest for his documentary, Growing up Springfield, from childhood to the present. Those profiled include Marge, Moe and Homer, who attempts to convince Declan and his crew that he is a millionaire. 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.
