The film uses the familiar Bollywood theme of siblings separated by fate. Gangland killers assassinate an honest man who defied them, killing his wife as well. The couple’s three sons flee the massacre and lose contact with each other. They grow up in entirely different circumstances and are re-united only when one of the sons, played by Dharmendra, sets out to find the villain who killed their parents….Their only hope of reuniting is by remembering the song their mother had taught them… Yaadon Ki Baaraat.
