Ostensibly a Central Asian war fantasy about a conflict between the Cossacks and the Tartars, Mehboob’s film proposes a tale advocating national independence. The Cossacks are oppressed by the despotic Russian king (Siddiqui) and his minister Jabir (Kayamali), who has Tartar blood in him. General Murad (Kumar) covertly sides with the opposition, gets arrested for treason and escapes. He meets the wild Gulnar (Sitara Devi) and gets her to spy as a maid of Princess Nigar (Bibbo). Nigar falls for Murad and Gulnar withdraws from the scene for the sake of her nation. Eventually Nigar, at the head of an army of women, helps defeat the villains.

Set in the Ottoman Empire, it deals with the Caesar's (Pande) army and its skirmishes with the local Muslim rulers. The Sultan's (Asooji) son Ziyad (Kumar) is arrested by the Roman army. The Roman princess Rahil falls in love with him. A Muslim maid Leela (Sitara Devi) and the princess help him escape. Long chase scenes and fights follow, which ultimately lead to success for Ziyad and his people.

Two devoted sisters find themselves in love with the same man, and in an act of sacrifice, one lets the other marry him. Life seems settled until a newcomer—a man with progressive, socialist ideals—arrives, challenging their traditional outlook and stirring emotions long buried. His presence forces both women to confront their feelings, question the choices they’ve made, and navigate the tension between duty, personal happiness, and changing social values, culminating in a quiet yet emotionally charged resolution.

In between his more ambitious Najma (1943) and Humayun (1945), Mehboob made this lightweight comedy about Justice Gangaprasad (Chandramohan) and theatre-owner Seth Badriprasad (Charlie) who lose their daughter and son respectively in the Kumbh Mela.

A dance film idealising poverty made mainly to showcase Bose's talents. Labour leader Suryashankar is jailed for trade union activities and, when released, finds that his friend Jagdish has stolen his property and plagiarised his play Bhookh (Hunger). To take revenge on behalf of the poor, Suryashankar's daughter Kumkum (Bose) marries Jagdish's son Chandan (Bhattacharya). Later she collaborates in staging a play meant to expose Jagdish's evil past. The film's publicity slogan was 'She robbed her husband to feed the poor!'

Thakur’s music-dominated debut tells of a love triangle involving the famous gramophone singer Sundardas (Surendra) who is happily married to Mohini (Prabha), and the even more popular singer Tilottama (Bibbo), who falls in love with Sundardas’s voice and wants them to sing a duet and have an affair. Ghosh Babu (Advani) is the manager of the record label.
