1935 film by Roberto Gavaldón

After her night shift ends, Adela goes on a drug-fueled, violent rampage of furious revenge on those who ruined her in this remarkably paced, audacious debut.

Based on the brief life of the Mexican composer of the famous waltz, "Over the Waves" ("Sobre las Olas"), Juventino Rosas.

Alfonso, Eduardo and Cristina get lost when visiting a forest. A strange monk finds them and takes them to an ancient convent. There, the three amigos suffer personality changes, specially Cristina who tries to seduce Alfonso in a strange coincidence to a story told by an old monk. After some efforts to escape, Alfonso is trapped inside a jail and more strange and macabre situations happen.

The Mexican Revolution is on its way when six brave peasants, known as "Los Leones de San Pablo", decide to join Pancho Villa's army and help end the suffering in their community by assisting in the struggle. After several battles and valiant heroics, the original group is eventually reduced to the leader Tiburcio Maya (Frausto) and young Becerrillo (Vallarino). When Becerrillo is infected by smallpox, Villa orders Tiburcio to kill him and burn the corpse. After reluctantly doing his duty, Tiburcio is ordered to leave the army, and returns home.
