Sunny Khanna, a struggling Indian actor, is settled in Britain with his huge family: his dad Kuldeep, his mom, his siblings, and other family members. Kuldeep's friend Dr. Verma seeks his permission for his niece Mahek to take up lodging with the Khannas for a month until he attends a conference in the U.S.; Kuldeep accepts. Upon Mahek's arrival she greets a dysfunctional family and attempts to change this by first assisting Sunny in pulling together his acting career, teaching Mrs. Khanna and her daughter-in-law to pay due respect to elders as well as upholding various religious practices of the Hindu religion with the first being Karva Chauth. Mahek also assists Jash Khanna in coping with the loss of his wife Christine and son Tobey in an accident by overcoming his alcoholism. By this time Sunny has fallen deeply in love with Mahek, but a confession leads to rejection and breaking hearts. The real reason behind this rejection comes to light when Sunny's grandmother passes away, changing the Khannas' lives forever.
