Yamla Pagla Deewana (2011)

Paramvir Singh (Sunny Deol) is a Non-resident Indian (NRI) living happily with his Canadian wife Mary (Emma Brown Garett) along with his two kids Karam and Veer and his mother (Nafisa Ali) in Vancouver, British Columbia, Canada. Years ago, after the birth of Paramvir's younger brother Gajodhar, Paramvir's father, Dharam Singh (Dharmendra) had run away from home and took Gajodhar with him, due to difficulties with the family. Back in reality, a Canadian comes to visit Paramvir at his home, where he sees Dharam Singh's photo. The Canadian recognises Dharam as a thief who had robbed him when he went to tour in Banaras. Upon hearing this news, Paramvir's mother sends him to Banaras to find his father, and younger brother.

When Paramvir reaches Banaras, he meets a youngster who cons him off all his money. Seeking help, Paramvir lands up at a bar, where he sees both Dharam Singh, and his brother Gajodhar Singh (Bobby Deol), who has now grown up. Paramvir realises Gajodhar is in fact the youngster who had earlier conned him, and is disappointed to see both his father and brother are con-men. When Paramvir sees Dharam alone, he confronts him and tells him his identity. However, Dharam refuses to acknowledge him as his son. Soon, Paramvir saves Gajodhar from getting attacked by goons, to which Gajodhar befriends him and accepts him to their team, not knowing that he is his elder brother.

During this time, Gajodhar falls in love with Saheba (Kulraj Randhawa), a Punjabi author. Dharam and Paramvir help him woo her, and the two start a relationship. Soon enough, Saheba's tough brothers find out, and beat Gajodhar up, and take Saheba back to Punjab. When Dharam sees that Gajodhar is hopeless, he breaks out, and asks Paramvir to help, and acknowledges that he is his father but he shouldn't tell Gajodhar anything about that, after which Paramvir and Gajodhar move to Punjab to get back his love.

Saheba's elder brother Joginder Singh (Anupam Kher)who is a cruel land of his village and her other brothers want to marry her to an NRI. Upon hearing this, Paramvir disguises Gajodhar up to make him look like a Punjabi, and they both go to Saheba's house, with Gajodhar pretending to be an NRI named Karamveer. On the other hand, Joginder has an arch-rival Minty(Puneet Issar) who wants to take Joginders place and doesn't want Joginder to win in upcoming elections. Joginder, after meeting both of them, decides that they would marry their sister to Paramvir, not to Gajodhar. However, Paramvir is already married. One night, Paramvir gets drunk and beats up Saheba's brothers but that only managed to worsen the matter. So Paramvir tells Gajodhar to run away with Saheba one night.

While they are making their escape, Dharam shows up with a band of musicians thus preventing Gajodhar and Saheba from running away because Dharam thinks Gajodhar is the one getting married but Saheba's family has chosen Paramvir. Dharam tells Paramvir and Gajodhar that Paramvir should be the one running away. So Paramvir attempts to go to the market but Poli brings him back home causing Joginder to think that Gajodhar and Dharam are joking as they said Paramvir is scared of marriage but unbeknownst to Dharam and Gajodhar, he is right behind them.

Joginder decides to get Poli married to Gajodhar which Gajodhar confesses to Saheba that he does not want at all and they will escape that very night. Again, they fail as Paramvir's wife Mary shows up with Karam and Veer (Paramvir's sons). Paramvir, Gajodhar and Dharam make up the story that she is their neighbour in Canada and that her husband is also named Paramvir who went missing last year. Mary knows that Paramvir is in front of her but chooses not to say anything because it will ruin the whole plan.

Joginder somehow finds out what has been on all this while and gets his men to attack Paramvir, Gajodhar and Dharam. Paramvir and Dharam beat his men up until Minty and his men show up. As Minty is about the attack Joginder, Gajodhar rescues him hence earning approval to marry Saheba instead of Paramveer. In the end, Dharam, Gajodhar, Paramvir, Mary, Saheba, Karam and Veer go to Canada where they live as one happy family.

Yamla Pagla Deewana 2 (2013)

In Varanasi, Dharam Dhillon (Dharmendra) and his son Gajodhar—or Prem (Bobby Deol)—are conning people into thinking that Dharam is a guru named Yamla Baba. When Yograj Khanna (Annu Kapoor) comes from England to meet Dharam, Dharam notices Khanna's diamond rings. Dharam and Gajodhar pretend to own a company, Oberoi, Oberoi & Oberoi. Impressed, Yograj begins to consider a match for his daughter Suman (Neha Sharma). Suman falls in love with Gajodhar, and a marriage is arranged in England when Dharam's older son Paramveer (Sunny Deol)—a loan-recovery agent for a bank—meets Khanna.

Paramveer appears at Khanna's club as Joginder (Dude) Armstrong (Anupam Kher) arrives to take it over, and beats up Armstrong's flunkies and goons. Grateful, Khanna hires him as his manager. Paramveer then finds Dharam and Gajodhar trying to swindle his boss.

Dharam and Gajodhar go to a house occupied by an orangutan, Einstein, whose absent owner (a disciple of Yamla Baba) has allowed them to stay there. The next day they go to Khanna's house for Gajodhar and Suman's engagement party, at which Paramveer is a guest. Paramveer meets art-gallery employee Reet (Kristina), with whom he falls in love. After Suman and Gajodhar are engaged, Gajodhar and Dharam discover that Reet (not Suman) is Khanna's daughter.

Although Gajodhar woos Reet, she is interested in Paramveer. Dharam claims to have another child, Prem's twin Q (Deol). When Q meets the Khannas he claims to be a painter, which attracts Reet.

Q unsuccessfully tries to produce a painting. During the night Einstein paints a beautiful picture, which Q passes off as his own. The painting becomes famous, and will be sold at auction. Paramveer makes changes to Khanna's nightclub, and Khanna wants Q to be his guest of honor. At the party, Reet asks Paramveer how he feels about her. Drunk, he tries to reveal Q's identity when he is distracted by Armstrong's goons. The next morning Reet goes to Paramveer's house but leaves, heartbroken, when she sees a girl sleeping with him.

Preparations for Prem and Suman's marriage are underway. Reet agrees to marry Q, and Paramveer wants a joint wedding. Dharam tries to convince Suman that Prem is impotent, and anyone who marries him will die in seven months. Despite this, Suman tells Prem that she loves him and Prem falls in love with her. When he goes to tell the truth to the Khannas, Armstrong's goons kidnap him, Dharam and the Khannas. Prem reveals the truth, Param saves everyone from the goons and proposes to Reet (which she accepts), and the film ends happily.
