Inn Galiyon Mein is a romantic social drama set in a lower middle-class neighbourhood of Lucknow, in a small locality where people of different faiths coexist and stand by each other in times of sorrow and celebrate Holi with as much joy as Eid. Hariya (Vivaan Shah) is a vegetable vendor who falls in love with another vegetable vendor, Shabbo (Avantika), who live in the same locality. However, Shabbo, an orphan, repeatedly dismisses his advances. The locality is also home to Mirza (Jaaved Jaaferi), a respected elder whose tea stall serves as a gathering spot for conversations and witty insights. Trouble begins when Ajay Tiwari (Sushant Singh), a local politician with ambitions of becoming an MLA, arrives to campaign for the upcoming elections. Sensing his ulterior motives, Mirza warns the residents, but what follows has far-reaching consequences.
