Now a lovely teenager, Heidi and four schoolmates are forced by the tumult of World War I into an Italian orphanage overseen by the evil Signor Bonelli. Together, the girls make a daring escape through the war-swept countryside. They travel over the Swiss Alps with the orphanage director just footsteps behind them. Captured at the summit, only Heidi's childhood friend, Peter, can save them and lead them home.
