Rani Mehra is a sheltered, meek, yet good-natured young Punjabi woman from Delhi. One day before her wedding, her fiancé Vijay (Rajkummar Rao) tells her that he no longer wishes to marry her. He explains that his lifestyle has changed after living abroad, and Rani’s conservative habits would be a wrong match for him. Stunned at the development, Rani shuts herself in her room for a day. Wanting to control the situation, she asks her parent’s permission to go alone on her pre-booked honeymoon to Paris and Amsterdam. After initially hesitating, her parents agree, thinking that a vacation might cheer her up.
In Paris, Rani meets Vijayalakshmi (Lisa Haydon), a free-spirited woman of French-Spanish-Indian descent, who works at the hotel in which Rani stays. Overwhelmed by the new city and having gotten into trouble twice – once with the local police and once with a robber – Rani intends to return to India. However, Vijayalakshmi helps her out and gives her a tour around the city. The two have a series of adventures, during which Rani relives the memories of Vijay patronizing her and forbidding her from dancing and drinking – which she’s free to do in Paris. During one particular incident, Rani tries on what she considers to be a revealing outfit and accidentally sends a selfie of her wearing the costume to Vijay instead of Vijayalakshmi due to the similarity in their names. She quickly realizes her mistake, but unbeknownst to her, the selfie regenerates his interest in Rani and Vijay decides to seek her out. Eventually, the time comes for her to bid an emotional farewell to Vijayalakshmi and board the Dutch Sprinter train for Amsterdam. However, when she arrives in Amsterdam, she finds that her hostel room is being shared with three men: Taka from Japan, Tim from France, and Oleksander from Russia. Despite being skeptical, she soon becomes good friends with them and spends time shopping, sightseeing, visiting a sex shop, going to a church, and meeting pole dancers in a club.
Rani befriends a pole dancer at the club, Roxette/Rukhsar (Sabeeka Imam), a Pakistani girl who is the sole bread-earner for her family back in Lahore and who is also a friend of Vijaylakshmi.
