### Premise
The story centers on Debi (Soumitrisha Kundu), who marries Rudra Roy Burman (Indrasish Roy), the son of Samaresh Roy Burman (Debesh Chattopadhyay). Debi's friend Maya (Koushani Mukherjee), known for her ominous presence, predicts that Rudra will die the day after the wedding, and the prediction comes true when he is murdered in the family home.[9](https://www.ottplay.com/review/kaalratri-review-soumitrishas-ott-debut-has-hoichoi-written-all-over-it/d5792ffde8356) • [1](https://hoichoi.tv/shows/kaalratri) Widowed the day after her wedding, Debi becomes trapped in the secrets and scandals of the Roy Barman family as the investigation unfolds.[1](https://hoichoi.tv/shows/kaalratri)
Season 1's six episodes move from the wedding-night murder (Bodhuboron) through the exposure of hidden scandals, Debi's questioned past, and the investigator Satyaki's probing of her shadowy history, ending with another murder and a final clue.[1](https://hoichoi.tv/shows/kaalratri) Season 2 continues the story in the Roy Barman household, where heirs die one after another, each murder following a mystery, while Debi's buried memories hold the answer she cannot access and Satyaki realizes the killer has been there all along.[10](https://www.justwatch.com/in/tv-show/kaalratri/season-2)
