Hollerin' Hank Cranforth becomes accidentally pinned under a pile of junk yard rubble. Lassie escapes and goes to get Timmy for help, but will it be in time to save Hank?...

Lassie swims a river to bring a rope to a runaway raft that's carrying Timmy and Geoff towards a treacherous man-made waterfall.

Lassie and Timmy try to save a young boy stuck on the edge of a cliff after Lassie's playful Jack Russell Terrier friend, Mel, moves a pylon and warning tape from the path of a kids bike race.

Hollerin' Hank secretly steals Lassie away from Timmy, but for what reason? Is it to help Lassie or hurt her?
