In San Diego 1969, child prodigy William Miller struggles to fit in. His life is further complicated after learning that his widowed college-professor mother Elaine has falsely led him to believe he is twelve years old. William is actually eleven, having started the first grade at five years old, and skipping fifth grade. Strong-willed Elaine's strict ban on rock music and her fear of pop culture have a lasting effect on her children, finally driving William's 18-year-old sister Anita to move to San Francisco and become a flight attendant.
