It is a movie (I think made in the ’90s). It opens with a bear, maybe two, escaping form a compound where they’re caged up. I think it was when someone was about to kill them?
There is a family with a younger brother and older sister who try to keep the bear, with a neighbor boy’s help, in their tree house. The neighbor boy agrees to keep the bear a secret if the sister will go on a date with him. I think the brother and sister live with just their father.
It is set in America or Canada I believe.
The movie isn’t Wild America or Alaska.
Thank you!
