GALI GULEIYAN is the story of a loner who loves to spy into people's homes and who gets easily troubled by wrong actions of people. Khuddoos (Manoj Bajpayee) lives in an apology of a home and runs an electronics repair workshop. He loves spying and has installed hidden cameras in people's homes to find out whether anything is amiss anywhere. He hears strange sounds of a boy being beaten up by his father in the neighbouring house but, strangely, the hidden camera does not capture any such act.
He often tries to strike up a conversation with young Idris (Om Singh) who, he thinks, is being beaten up, but Idris doesn't pay attention to Khuddoos' moves. Idris lives with his parents, Liyaqat (Neeraj Kabi) and Saira (Shahana Goswami). Idris has a little brother, and his mother is expecting another child. The new-born is still-born and a distraught Idris blames dad Liyaqat for the demise as he feels that Liyaqat had been ignoring mother Saira for his mistress, Noor (Shruti Sharma).
Does Khuddoos finally confront Idris? Is Idris actually beaten up by Liyaqat? Are some of the question that forms the rest of the film.
