Anand (Kishore Kumar), a
Punjabi boy comes from
Jalandhar to
Delhi, but is unable to find a place to stay, as everywhere he goes people want to give room only to a person of their region. Desperate, Anand masquerades as a
Tamilian, Anand Kumaraswamy, and finds a place to stay with a Tamilian family. There, he meets the daughter of the South Indian Cultural Association Head, Janaki (Vyjayantimala). A Romance develops, but Anand is unable to reveal his true identity to her. Daulatram Khanna
Nazir Hussain, Anand's father and Janaki's father, Subramanyam's (Nana Palsikar) superior, gets transferred to Delhi. Anand's sister Nikki (Jabeen) comes close to Anand's friend, Ashok Banerjee, a
Bengali painter who teaches her art. Anand makes his Tamilian servant Kumaraswamy (Dhoomal) masquerade as his father and they even meet Janaki's father to discuss the marriage. But soon they are found out and Daulatram opposes the marriage. Daulatram also faces opposition from his community who come to discuss Nikki's marriage within the community. Subramanyam too turns against his daughter, who tries to kill herself. She is saved by a kindly shop owner (Radhakishen) and passed off as his Punjabi niece, Mohini. Both Subramanyam and Anand are kept in the dark and are convinced Janaki is no more. Subramanyam realizes his mistake, but sadly he thinks it is too late. Thinking Mohini to be a good Punjabi girl, Anand's family readily agrees to his marriage with her. Daulatram returns home to find Ashok consoling Nikki and throws him out. Nikki's marriage is almost called off when the boy's father demands a huge
dowry. Ashok offers his family jewels to Daulatram so that Nikki's marriage can take place. Daulatram's eyes open and he calls off the wedding and marries Nikki to Ashok. The truth about Janaki/ Mohini also comes out and now that both groups have shed their prejudices Anand marries Janaki. ==Cast==
