Lassie At Last (a.k.a. Incident In Glenridge) - S1.E1

The beloved collie finds further adventure in California. In the opener, Uncle Steve (Jon Provost- who played Timmy in the original series) is shot while walking in the woods with Lassie. The culprit is a deer hunter out of season who proceeds to blame Lassie for a false bite so the dog can't lead to Steve's whereabouts.
