Charlotte "Charlie" Newton is a bored teenage girl living in the idyllic town of Santa Rosa, California. She receives wonderful news: Her mother's younger brother (her eponym), Charles Oakley, is arriving for a visit. Her uncle arrives, and at first, everyone is delighted with his visit, especially young Charlie. Uncle Charlie brings everyone presents. He gives his niece an emerald ring that has someone else's initials engraved inside. Charlie's father, Joseph Newton, works at a bank, and Uncle Charlie tells him he wants to open an account and deposit $40,000 ($ million today) at his bank. Two men appear at the Newton home, posing as interviewers working on a national survey. Uncle Charlie is upset and berates his sister for opening up her home to strangers. One of the men takes a photo of Uncle Charlie, who demands the film roll because he wants to avoid having his photo taken at any cost. The younger interviewer, Jack Graham, asks out young Charlie, and she guesses that he is really a detective. He explains that her uncle is one of two suspects who may be the "Merry Widow Murderer".
