The Little Girl Who Lives Down the Lane (1976)

Synopsis
In this Canadian thriller, Jodie Foster plays the title character, a reclusive, fiercely self-reliant teenager who lives alone in her father's house. When visitors call, Foster explains that her father is away on business. He's away, all right...far, far, away. And Foster, determined not to lose her independence, will go to any lengths to protect her secret, a fact that nosy neighbor Alexis Smith learns to her regret. A new danger to Foster's well-being looms in the form of pedophile Martin Sheen, who schemes to place the girl in a compromising position. Offering a helping hand to Foster is misfit teenager Mario (Scott Jacoby). Laird Koenig adapted his own novel to the screen. ~ Hal Erickson, All Movie Guide
