Nakkash is the story of a gifted Muslim craftsman Alla Rakkha Siddiqui. Alla Rakha is a widower who has a son, Mohammad and a best & only friend Samad in the name of a family. Alla Rakha believes in no religious boundaries and uses his craft of engraving in the Hindu Temples. For that he gets boycotted by his community; Mohammad doesn't get admission in Madarsa & he faces a lot of oppression from both the communities as the film progresses.
Samad who is a poor e-rickshaw driver, wants to send his to holy Hajj but has no money for that. Samad steals the Temple trust's gold from Alla Rakha's custody. Alla tries to keep Samad out of this situation but Samad goes to jail for it.
A year later Alla gains popularity as a symbol of accord with a news article for which Munna, an aspirant Hindu politician loses his election ticket. What happens to Alla, a cast-off from his commune and disdained from Samad & Munna is the tale of Nakkash (The Craftsman).
