Hundreds of kilometers away, a young genius scientist boards the luxurious Maharajas' Express.
He is going to visit his maternal grandfather, who has promised homemade sweets, mangoes, and special tea.
The scientist carries a science kit, telescope, physics notebook, and pocket robot.
Grandpa calls.
"Where are you?"
"On the train."
"Don't be late."
"Nothing can stop this train."
The universe immediately takes that as a challenge.
