When forbidden love tears a tightly knit Indian family apart, a mother's heartbreak prompts her son to reunite the shattered clan in this family drama from filmmaker Karan Johar. Business tycoon Yashovardhan Raichand (Amitabh Bachchan) has everything a man could ever want: a loving family, a thriving empire, and a beautiful wife.
When Yashovardhan's son Rahul (Shah Rukh Khan) discovers that he is adopted, he expresses his gratitude through unwavering devotion and unending loyalty until the day that he falls in love with a boisterous young outcast named Anjali (Kajol). Disowned by his father and left to his own devices, Rahul gathers Anjali and her young sister, Pooja (Kareena Kapoor), and sets his sights on London.
As the grief of Rahul's mother becomes too much to bear, Rahul's brother Rohan sets out to find his brother and reunite their fragmented family.
