The Slender Thread

When psychology student Alan Newell (Sidney Poitier) takes a call at the crises center he volunteers at, he discovers that the woman on the other end, Inga Dyson (Anne Bancroft), has taken a lethal dose of sleeping pills in an attempt to escape the misery that her life has become. As Alan struggles to keep Inga on the phone long enough for help to reach her, she relates to him the incidents that drove her to her suicide attempt.
