The D'Souza and Chaddha families are neighbors and have been good friends for as long as they can remember; despite their diverse religious and cultural beliefs, they celebrate Diwali and Christmas with cheer and gusto. Then Anjali Chaddha and Steven D'Souza fall in love, and this brings an end to the friendship. Anjali and Steven elope, marry, and re-locate, leaving the two families to live with bitterness the rest of their lives. 27 years later, a young man claiming to be the son of Anjali and Steven comes to visit his paternal and maternal grandparents, and is cold-shouldered by both families. He persists and wins over the hearts of all his grandparents, but before he can win over his Jassi mama and Moses chacha, they find out that Raja is not who he claims to be.
