Mr. Sameer Seth, on being hit by a hard object, loses his memory and suffers from amnesia. He forgets persons and their names. People call him 'Mr. Somersault,' as the sound of 'samarsath' quite matches with the noun 'somersault,' which means 'turtling down up like a boat.'
He finds a job as a manager at Delhi Paradise, a famous hotel in Delhi, which belongs to his father late Mr. Hemanth Seth's friend Mr. Adithya Goel.
Five important guests, among others, stay at the hotel. Their lives are in danger, as they have some conflicts with others.
One day, Mr. Sameer is at the reception, as the receptionist has gone out for some time. Seven different visitors come to see some guests staying in the hotel. On that day, two guests are killed. Then the real troubles for Mr. Somersault begin, as the police suspect him to be behind the crimes or that he did something to upset the act.
What does he do? Do the police leave him? Do the police catch the real killers?
