Nikhil (Sidharth Malhotra) is a businessman whose girlfriend Karishma (Adah Sharma) is an actress. Nikhil is a guy who believes once you are committed to a girl, there should be no straying. He is the guy every girl would love to have. Karishma asks Nikhil to arrange INR 5 crores before marriage, which is 7 days later. In mean time Nikhil meets Meeta (Parineeti Chopra), Karishma’s younger sister, with whom he had a brief encounter 7 years ago. Meeta, who is an IITian in chemical engineering, is super intelligent and believes in bringing change to the world. She has no limits and goes on to do what her heart says, which is typically opposite of Nikhil. They spend 7 days together and develop an untold love.[
