Rajveer Singh, a cop from a village in Punjab, has the sole dream of becoming a supercop and wiping out all crime. After training, he gets his first posting in Mumbai for a special assignment. On arrival, he is disappointed to find that his first job is to protect a nine-year-old boy, Abbas Khan as he considers it a menial job.
Abbas is the sole heir to millions of riches left to him by his parents, who died in a plane crash. The only threat to Abbas's life is Nazir, who is responsible for the plane crash that killed Abbas' parents. Nazir's father was helping terrorists in secret. Nazir blames Abbas' father for the murder-suicide of his entire family carried out by his own father.
Abbas's only guardian is Sapna, a successful model, who is close to Abbas and his family. Rajveer and Abbas hate each other from the word go. Rajveer dislikes the spoilt brat for being the cause of his shattered dream of becoming a supercop whereas Abbas hates Rajveer for curtailing his freedom for security reasons. Abbas then calls Sapna, to handle Rajveer's restrictions and together they play pranks on Rajveer to get rid of him. From here starts a very interesting love-hate relationship filled with fun and laughter, only to culminate in Rajveer and Sapna falling in love with each other and Abbas and Rajveer developing a relationship of understanding by the end of the day where Rajveer is ready to risk everything to protect Abbas from Nazir, the only danger in Abbas's life.
Nazir makes several chilling attempts to eliminate Abbas. Now the only way to get Abbas out of danger is for Rajveer to nab Nazir. Rajveer kills Nazir in a thrilling climax, rescuing Abbas and uniting with Sapna.
