La soldadera (1967)

While waiting for a train which will take them on their honeymoon, two newlyweds, Juan and Lázara, are separated by a federal army commander who is going around enlisting men to fight against the revolutionaries. Traveling with the troops, Lázara follows Juan until he dies in a battle against the Villistas. From that moment on, the young woman's fate will be in the hands of whoever happens to win the latest contest, an uncertain fate for someone whose only wish is for a home of her own.
