While penning the script he stated he had to change many scenes of the film because he felt they were becoming too similar to his previous film, Jab We Met. In the April 2013 interview with the same, he said the film is primarily the story of two characters from very different backgrounds— played by Randeep Hooda and Alia Bhatt—who take the road trip across six states in a truck.
Further, Ali told that he had thought of making Highway in various ways.
Veera Tripathi (Alia Bhatt) is the daughter of a Delhi-based rich business tycoon.
One day before her wedding, she is abducted from a petrol station off a highway, while her fiancé - who she did not really love, sits in the car convulsed with fear.
The film ends with Veera looking at the mountains, then the sky.
