Guest iin London

The film revolves around Aryan Shergill (Kartik Aaryan) and his girlfriend Anaya Patel (Kriti Kharbanda) life, which takes a turn when uninvited guests visit them in London.

Aryan Shergill is a migrant worker in the UK, but his working visa expires. He resolves to arrange a sham marriage in order to obtain indefinite leave to remain, and ultimately British citizenship. He chooses Anaya (a taxi driver), promising to give her £7,000 in return. They conspire to have a fake marriage by lying to the court. Aryan takes Anaya to his home to make the court believe them. A few days later, Gangasharan and Guddi (Chacha and Chachi ji) visit them, telling them that they are Aryan's relatives. He takes them home, and makes Anaya somehow accept them for a few days. Chacha and Chachi ji get Aryan and Anaya married. On their marriage night Aryan gets drunk and confesses his love to Anaya. Some days later Anaya also tells him that she loves him and things start smoothening somewhat.

Aryan then introduces Chacha ji to his boss. When Chacha ji subsequently visits Aryan's office, he accidentally turns on the filter, which is out of order, making the boss have a current shock. The next day, Aryan-Anaya and the guests are invited to his office party, where Chacha ji notices Aryan's boss harassing his secretary, and stops him, bywhich Aryan loses his job. Shortly thereafter the couple starts getting irritated by the visit of Chacha and Chachi and try multiple methods to send them away. One day Aryan and Anaya spot something mysterious about them, seeing them lying about their whereabouts, and visiting some other place and other person. They check their luggage and find old newspapers detailing the 9/11 attacks, which makes the two suspicious. So Aryan, one day takes them to a cafe and leaves them there, and returns home. By then, Anaya gets a courier from neighbours and they open to find that Chacha and Chachi ji came to collect their son's belongings. The couple visit their son's boss and they learn that he died in the 9/11 World Trade Center attack and 100000 pounds given in insurance was transferred by Chacha ji to Aryan's bank account.
