Ami Sei Meye (2011)

Eighteen years back Samrat and Banani Sen adopted a baby girl. They named her Kajol. With time this vibrant, innocent girl became the darling of the family. You must be thinking what's so uncanny about it? It's only natural that in these eighteen years Kajol has grown up to be the much loved Barbie of the Sen Family. Indeed she has - However this truth has a dark past. Though Kajol's father Pronoy is Samrat's elder brother, lust for money didn't stop Samrat from conspiring against Kajol's parents. He sent Pronoy to an asylum and compelled Kajol's mother to walk out of the Sen mansion leaving Kajol behind. In reality Kajol's adoption has only been Samrat's facade to hide his hideous crime and intentions.
