Jamai 420 (2015) Plot Summary Explained

Joy Chowdhury, a divorce lawyer, is in love with his assistant, Priyanka, who is also a lawyer. Joy's rival, Sumanta, also loves her. Sumanta always loses cases against Joy due to the latter's smartness, even failing to win Priyanka's heart; he's despised by his mother. Joy is always afraid of his father, Rajballabh, a retired C.J., when it comes to talking about his and Priyanka's marriage, frustrating Priyanka. Priyanka's father, Dhanakrishna, is a blind widower with strong senses. A land promoter, Raghab Roy, is friends with Rajballabh, and a palanquin supplier, Charandas. Bijoy, Charandas' son, loves Julie, whose brother, Potla Poda, is a gangster. But his father has fixed Bijoy's marriage with Tina, whose father, Raghab, is weak-hearted and suffers a stroke every three months. Tina loves Shaan, a dim-witted simpleton, and has objections to this marriage.

After arriving in Delhi and reaching Charandas' residence, Joy and his family learn that Bijoy has eloped with Julie, which Raghab's family also discovers. Therefore, Joy's father decides that the marriage should take place. While Bijoy marries Julie through a court marriage and succeeds, Tina doesn't, as she had to marry Joy instead, despite her plans to introduce Shaan as the groom. Sumanta also learns about their marriage through Chowki, Joy's family servant, telling this to Priyanka. Shaan and Priyanka learn about their marriage and start misunderstanding Joy and Tina. Shaan even resorts to self-destruction and lives an alcoholic life. Meanwhile, Julie's brother learns of his sister's elopement with Bijoy and their court marriage, leading to trouble for Bijoy. Even Bijoy's parents also disapprove of their marriage because of her religion and her family. After this, they flee to Bangkok.

Bijoy hatches a plan under the pretext of a honeymoon trip to Bangkok; Joy and Tina meet Shaan and Priyanka, respectively, clear their misunderstandings, and they cooperate in the plan before Joy's father can arrange a get-together. Sumanta learns of the couple's honeymoon, but witnessing them and Priyanka together, he sets out to uncover the truth. After reaching Bangkok, the three couples book respective rooms in a hotel. Living in different rooms, Bijoy, Joy, and Shaan argue with their lady loves regarding their marriages despite living together. Sumanta also lands in Bangkok and appears at the hotel, where the couples live, to find out about their relationship, as well as Julie's brother, who is here to find out about his sister's relationship. There are so many hilarious consequences and comedy of errors when the three men woo their lady loves, while Joy and Tina manage to hide their real relationships from their respective in-laws. Will Joy, Bijoy, and Tina be able to reclaim their love along with their families' approval?
