Hector Valenti, star of stage and screen, comes back into Lyle's life. Valenti, devoid of a partner to work with, has been starving. Seeing Lyle and the Primms in the park, he holds back from revealing himself because he is so ragged-looking. Instead he concocts a scheme to pretend to help Lyle find his mother in order to get him back in the act.
The Primms are suspicious, but Lyle wants to find his mother. He imagines what she could be like (in his dreams, she's a lot like Mrs. Primm) and soon can think of nothing else.
The Primms try to distract him with many activities, but in the end he must go. He and Valenti raise enough money to live well again, but Lyle finally makes Valenti initiate the search. In the end, Lyle finds his mother and happily brings her back to the Primms's house to live.
