A short plot description on letterboxed.com:

Paro loves Shankar, but Shankar loves the bottle more. Sadness, shame and self-sacrificing ensue. But does anyone do broken hearted innocence like Nimmi? Not even sudden palatial wealth and snazzy gowns can take that away from her because there's always a windswpt meadow to wander through or a column to mournfully lean against. Incidentally, Shankar read the same book on how to be a tragic lover.

The Encyclopedia Of Indian cinema has this to say about Daag:

In Chakravarty’s melodrama about class
division and the evils of alcohol, Shankar
(Kumar), a nice village youth who makes clay
statues, is parted from his sweetheart Parvati
(Nimmi) when her family inherits a fortune. In
addition, he is an alcoholic who devotes all his
wealth, property and even the money for his
ailing mother’s medicines on drink. The
maudlin plot comes alive only through Nimmi’s
uncanny knack for larger-than-life gestures.
The film’s remembered song is Talat
Mahmood’s Ai mere dil kahin aur chal.

Dilip Kumar won a FilmFare Best Actor award for Daag.

Daag was the 4th highest grossing film of 1952 after Aan, Baiju Bawra and Jaal.
