Star Plus’ Ek Hasina Thi, the thriller by Cinevistaas that started airing last week, has managed to completely take viewers by surprise with its gripping storyline. With the show getting straight to the point rather than beating around the bush, the response has been really positive from the masses. Durga (Sanjeeda Sheikh), who is out to take revenge of her sister’s injustice at the hands of Shaurya (Vatsal Sheth), will decide on her first target in the upcoming episodes. And the man who will be the prey to Durga’s strong avenge mission will be the Goenka’s right hand Navin Mathur (Amit Behl), who has been supporting Shaurya the most. Durga will go to the Goenka office and work on her task of getting to Mathur’s cabin. She will make sure that he has to leave office for some work and in the mean time she will set off the fire alarm for the other employees to get panicky and leave the office premises. Informs a source, “Durga will get into the cabin of Mathur and start copying the entire data from his computer.” On the other hand, unaware of Durga’s intention Sakshi (Simone Singh) will be tensed for the latter. And with the fire alarm going off, she will further panic not finding Durga in the premises and will frantically search for her. Will Sakshi catch Durga red handed and what will lie ahead in Durga’s plan? Since Sanjeeda was busy shooting, she remained unavailable for comment.
