The Alfred Hitchcock Hour: Night Caller

Marcia Fowler is sunbathing in her backyard when she spots a new neighbor, Roy Bullock, eyeing her. Frightened, she calls the police, who take her to the Bullock house and warn Roy not to be a peeping Tom. Marcia also asks her husband Jack to admonish Roy, but Jack finds Roy to be friendly. Roy befriends 12-year-old Stevey Fowler. Marcia begins getting obscene telephone calls, and blames them on Roy. When Jack and Stevey take a flight to San Francisco, Roy visits Marcia to leave a gift for Stevey, and to chide Marcia for her infidelity. Panicked, she overreacts, and soon regrets her rashness.
