London-based Kanav Chhadha is pressured by his parents to marry Amritsar-based Ashmeet Kaur, the non-graduate daughter of Sujan Singh, a childhood friend of Kanav's dad. The engagement takes place in the Soni Darbar, and the families, together with friends, board three train coaches - duly decorated for the occasion - to travel to Mumbai for a five-star wedding and reception. The couple have a room to themselves and decide to share their feelings while the rest of their respective families and friends sing and dance. Kanav finds out that she is in love with Kuljit Singh, a Gurdwara singer, but her parents do not approve of him as he is not wealthy, sophisticated, and does not even know how to wear a Pagdi properly, while he confides that he is not yet ready for marriage. Hilarious chaos results when the duo decide to make their incompatibility known to their respective parents.
