Desperate Lives was a 1982 made-for-TV film about drug use in a high school. The film has a very strong anti-drug message and was very popular with my After School Special obsessed older sister. I have no idea how many times it was broadcast, but it would be a safe guess to say that we watched it every time it was on.
I remember it not for its strong anti-drug message (and its strong), nor for its Rick Springfield theme song. No, I remember it for the reason everyone remembers it, for the scene in which Helen Hunt (well her stunt woman) jumps out a window after a drug freakout.
Wait for it at the end of this trailer. It is worth the wait.
