A full-scale stunt movie. The crooked trustees of Lala Niranjamal's estate try to eliminate its two heirs: the daughter (Aruna Devi) is jailed and the son becomes a penniless wanderer. When released, the daughter becomes the mysterious Deccan Queen, nemesis of evildoers. The plot gets complicated when a clerk in an insurance company, Vrinda (Aruna Devi again) , turns out to be the wanted woman's double. Vrinda falls in love with Inspector Suresh (Surendra), but then later so does the Deccan Queen. The triangle takes unusual turns when the queen impersonates Vrinda and demands that Suresh marry her at once.
