On the last day of their Aspen vacation, a lovely French couple named Oliver and Sophia take their precious young boy Timmy on a day trip up the majestic mountain. The family's idyllic excursion turns disastrous when the parents become separated from their son after an unexpected blizzard quickly descends upon the resort town.

The worst day of Oliver and Sophia's life becomes the first day of Timmy's amazing adventure in the wilderness of the mountain; for the lost boy is rescued by a ragtag family of kind animals who bring him back to their hidden cave and raise him as one of their own.

Timmy's time with the animals teaches him about survival, love and loyalty and defines what it truly means to be part of a family.
