Ramakant (Rajkummar Rao) is a miserly perfume shop owner who lives with his wife, Shilpa (Sanya Malhotra). They are tenants of Mrs. D’Souza (Seema Pahwa), who lives in the same building with her son, Glen (Abhishek Banerjee). The couple attends a wedding and gifts the newlyweds a toaster worth ₹4,999; however, when the marriage is dissolved only a day later, Ramakant decides to reclaim the gift without telling Shilpa. He is informed that all wedding presents have already been donated to an orphanage. Nandini (Farah Khan), the head of the orphanage, refuses to return the toaster as it is already in use. That night, Ramakant’s attempt to steal it fails, but Glen successfully steals the device shortly after.
The following day, the police arrive at Ramakant’s house after Nandini reports the theft and names him as the prime suspect. Meanwhile, Ramakant spots Glen carrying the toaster to a mall to meet a mysterious man. Shortly after, Mrs. D’Souza passes away. While visiting her home, Ramakant finds the toaster and attempts to take it, but a drunken Glen confronts him. During the ensuing scuffle, Glen accidentally falls from the balcony to his death. An elderly neighbor, Malini Pherwani (Archana Puran Singh), films the incident and uses the footage to blackmail Ramakant into a sexual relationship. Ramakant’s frequent nights away from home begin to strain his marriage with Shilpa.
Desperate, Ramakant asks his perfume supplier, Guddu (Vinod Rawat), to intervene and deal with Malini. However, Malini overpowers and kills Guddu, forcing Ramakant to bury the body. Inspector Balagode (Upendra Limaye)—the man Glen had met at the mall—investigates the disappearances while secretly searching for the same toaster. He suspects Ramakant after Nandini checks in on the theft case. When Balagode attempts to arrest Ramakant, Malini intervenes by paying Nandini for the toaster to drop the charges. When the Inspector later confronts Malini, she seemingly kills him and once again forces Ramakant to dispose of the body.
Shilpa, having secretly followed them, confronts the duo as they attempt to bury Balagode in the same grave as Guddu. To their shock, Balagode is still alive; he holds them at gunpoint, revealing that the toaster contains an SD card with an incriminating video of a high-ranking politician. Unknown to him, Malini had also hidden the footage of Ramakant on the same toaster.
In a final brawl, Malini kills Balagode but is subsequently killed by Ramakant and Shilpa in self-defense. The politician arrives with his henchmen to retrieve the evidence. Ramakant hands over a card, which the politician destroys before letting the couple go. However, Ramakant reveals to Shilpa that he tricked the politician into destroying the blackmail footage of himself, while keeping the politician's evidence as leverage. The couple reconciles and hitches a ride home.
