Dhairyam starts with a UG college setting, where the lecturer asks this question of his degree students: If the Kakatiya Express is going at 120kmph, in how much time will it reach Chennai, which is 600km away?

Is it going by bus, train or flight?
Does it have the habit of stopping to ask for directions, or is it over-confident?
