The film depicts the life of a truck driver Sucha Singh (Gurdeep Singh) and his wife Balo (Garima). Balo has to get Sucha Singh's food ready every day, walk a long distance through the fields and wait for him on the highway as he drives past the village. He leads an independent life, playing cards with his friends and spending time with his mistress, and comes home only once a week. However, he expects his wife to play the traditional role. One day Balo gets late, trying to save her sister from the advances of a lecherous villager. Sucha Singh is angry, and drives away without his food. She decides to wait for him until nightfall.

The film was shot on location in a Punjab village. Still photographer Navroze Contractor helped Mani Kaul in his search for the right location. During this time, they also had long discussions on black-and-white, lenses, light, etc. Later, Contractor was to be Kaul's cinematographer for his third film Duvidha.

John Abraham, who subsequently became known as a filmmaker, started his career by assisting Kaul on Uski Roti.

Uski Roti marked a major departure from the conventions of narrative cinema, dispensing altogether with plot in the usual sense. Kaul also did not use any established film actors. There is little dialogue in the film. The dialogue is delivered in undramatic monotones, somewhat reminiscent of the films of Robert Bresson, whom Kaul acknowledged as a major influence. The camera, wielded by K. K. Mahajan, dwells on faces, hands and exteriors - mud walls, a windswept highway, a guava orchard. The emphasis on hands is particularly Bressonian. In the words of Derek Malcolm, "The film is not an orthodox narrative, dealing instead with silence, mood and imagery." In a 1994 interview, Kaul said, "When I made A Day’s Bread, I wanted to completely destroy any semblance of a realistic development, so that I could construct the film almost in the manner of a painter."

Due to its radical departures from the prevalent cinematic norms, the film did not get commercial theatrical release. However, it did win the debutant director the 1970 Filmfare Critics Award for Best Movie, and also won Mahajan his second National Film Award for Best Cinematography. Subsequently, it has been recognised as "one of the key films of the New Indian Cinema or the Indian New Wave".^[6] Shyam Benegal considers it "as much a landmark as Pather Panchali".^[7] In recent years, it has received renewed appreciation, being screened at retrospectives, aired on television channels such as Channel 4, and also distributed in DVD form. A reviewer for Channel 4 writes: "Mani Kaul takes us on a moving journey into the internal life of his protagonist, and KK Mahajan's cinematography will linger long in the viewer's mind."^[8] In a 2009 book on Indian cinema by Ashish Rajadhyaksha, an entire chapter is devoted to Uski Roti.^[9]
