Thendral Vandhu Ennai Thodum () is an Indian Tamil-language television series that premiered on Star Vijay and streams on Disney+ Hotstar. It is the remake of the television series Khelaghor, which is aired on Star Jalsha, however the plot eventually deviates.
The first part revolves around how Abhinaya, a traditional girl, who upholds her traditions and customs, crosses paths with Vetri, a rogue who is ignorant about the importance of traditions and marriage. The story revolves around Vetri tying the thali with Abhi in the heat of an argument at the temple, and whether the pair find love along the way.
The second part is taken six years after Vetri accepts his murder charge and is released. When he gets out and tries to find Abhi, he learns she has aborted their child and moved far away. Two years later, Abhi is now a high-ranking collector, whilst Vetri is a notorious rowdy in Kanchipuram due to his breakdown over what he found out about his child. However, Abhi didn't abort the child (Sudar) and is adamant on ensuring Vetri doesn't see her. How the pair are brought closer through Sudar forms the premise for the second part of the story.
Plot
Part 1 (Episodes 1-454) An unforeseen incident forces a traditional girl to marry a rogue. Despite their differences it is possible that love will blossom.
Abhinaya's (Abhi's) family is introduced and it shown that she has returned from the United States in order to marry her fiancé, Dharshan. Vetri is a village rowdy who works for Poongavanam. Vetri's mother loves him, whilst his father detests him for going down the wrong path when he was an excelling student. Abhi and her family decide to go to the temple to ensure her wedding goes well; Vetri is on his way to the same temple on Poongavanam's order, as his driver has eloped with a minister's daughter and plans to marry her at the same temple. In the temple, a sage encounters her and predicts that Abhi will wed an rogue, whether they had previously given it any credence. Abhi assists the eloping couple in getting married and the pair do, however Vetri arrives and threatens the newly-wed couple, even attempting to take off the thali that the driver's wife has on. Abhi intervenes and slaps Vetri for continuously attempting to take the thaali off them. In the heat of the argument, Vetri takes a thali off the Thirunankata Amma and ties it around Abhi and leaves. Her family are shocked, as well as Vetri's gang.
A livid Surya decides to file a police complaint against Vetri and the police arrest him. Meanwhile, Sankar Narayan forbids Abhi from entering the house unless she takes off the thali. Abhi's family convince her to undergo rituals to get rid of the thali and she complies, but then realises she has faith in the thali as it was given by God. Abhi refuses to take off the thali and leaves her house - to the anger of her father and the rest of the family barring Padma. Abhi gets Vetri out on bail, but Vetri is not grateful and tells her to get rid of the thali and Sankar Narayan disowns her. A different sage also foretells that Vetri will marry a girl and she will bring prosperity into his life.
Abhi forcefully ushers herself into the slums of Kanchipuram and waits for Vetri outside his house, waiting in the rain and resisting Vetri's friends attempts to usher her away. However, the next morning, Senba (Vetri's rival) ogles and harasses Abhi - leading Kamala to bring her into their house.
Vetri initially dismisses Abhi's attempts to help him comprehend the meaning of love, but Abhi discovers the truth about Vetri and the reasons behind his abrupt change, as well as the fact that Radha, a lifelong acquaintance, is secretly in love with him.
Destiny causes several things to happen in the lives of Vetri and Abhi that finally lead to the two of them becoming close. Vetri mentions that he likes Abhi in the scene when they were both separated from each other and forced to marry other people - Vetri marrying Radha and Abhi marrying Shakthi, a childhood friend of hers. They end up cancelling their respective marriages and confess their feelings to each other and accept each other as husband and wife.
However, Kamala forbids the pair from entering the house after bringing shame to her at the wedding, whilst Vetri's other family members agree to let them live with them on the terrace next to their house.
Part 2 (Episode 455 onwards) After being separated for years, Abhi and Vetri cross paths again.
