Son of Sardaar 2 is the sequel to Son of Sardaar (2012), where years after settling his epic family feud and surviving house arrest in Punjab, Jassi Singh Randhawa (Ajay Devgn) returns to London to restart life, where he meets his wife, Dimple (Neeru Bajwa), who wants a divorce to marry her boyfriend. To fight his case, Jassi accidentally meets Rabia (Mrunal Thakur), thinking that she is his lawyer. Upon learning the truth, Rabia keeps Jassi as her tenant. To make matters worse, Jassi gets to know that Rabia is a Pakistani who stays with her sister and niece, Saba (Roshni Walia). Roshini loves Goggi (Sahil Mehta), who belongs to an anti-Pakistani, Indian conservative Punjabi family. Knowing that Goggi's family won't approve of Saba as their daughter-in-law, Rabia requests Jassi to make this marriage happen by posing as Saba's father and a former army man to gain the groom's parents' approval for their marriage. What follows next is a series of hilarious situations and misunderstandings that leads to a one-of-a-kind wedding.
