Snowbound Train: Hoarding to Survive

While traveling with her parents, Clara Linden's bullet train is trapped in the mountains by a massive blizzard. Her cousin, Tanya Carter, steals their supplies and pushes Clara and her parents off the train to their deaths. Reborn just before the train's departure, Clara uses her memories to frantically hoard supplies, upgrade to a sleeper cabin, and cut ties with her ungrateful cousin. She protects her parents through the crisis, exposes her cousin's evil deeds, and ultimately survives until rescue arrives, giving her family a second chance at life.
