Rupkothar Kahini (The Grandfather Paradox)
Basudeb Roy (played by Barun Chanda) tries to make a call from his newly received mobile phone. He finds that everytime he tries to make a call, the phone asks for a date and time in the past. Basudeb now keeps on calling his missing granddaughter (played by Dipanwita Bhattacherjee) in a past date and time in order to save her.
A sci-fi portraying the belief of Basudeb Roy and his persistence in protecting his granddaughter Rupkotha, the film presents itself in an arena of positive thoughts and their subsequent consequences in the framework of time.
