All hell breaks loose when a giant grizzly, reacting to the slaughter of her cubs by poachers, attacks a massive rock concert in the National Park. [This sequel to "Grizzly" (1976) was left unfinished after production wrapped prematurely in 1983, and was not officially released until 2020, though a bootleg workprint version had been in circulation for some years prior to this.]
Just. Wow.
This movie is cobbled together from some concert and nature stock footage mixed in with a less than half finished movie about a bear hunt. At no point do you see a bear and a person onscreen together. So many celebrities show up in this movie, but the real star of the film is all the terrible editing.
