Based on the successful Finnish drama: Veera, Jayati and Kavita, tired of abusive and unloving husbands, plan and execute the murder of their husbands in what they make look like a boat accident. It was an almost perfect plan, as the boat blew up mid sea, when the three couples had gone for a quick vacation, in what looked like a simple boating accident. It's a secret the three women share, a secret that will help them move on from the drudgery of their unhappy lives. The police investigation led by Inspector Pankaj Misra and Inspector Rinku Sharma do not suspect the 'grieving widows'. The story of the accident begins to unravel when the innocent boat blast is confirmed by forensics to be a bomb blast. To add to the women's problems - Rameez, Veera's husband Jatin's business partner - believes that Jatin has hidden some money that belongs to him.
