Rani (Vyjayanthimala), a feminist, is best friends with Kamini (Anjali Devi), much to the disapproval of her mother, since Kamini's father (Chittor V Nagaiah) had married a woman of low caste. They meet Raja (Bharat Bhushan), a medical student, and Kishore (Kishore Kumar). After the initial tussle, Raja and Kamini fall in love while Kishore likes Rani. Rani goes to Colombo for the University Sports Tournament, and while winning every single event she enters there, she injures her leg and is in hospital. Meanwhile, Kamini and Raja marry secretly, since he knows his woman-hating, upper caste father will never agree to this marriage. Captain Sundar, Kamini's childhood friend, comes from Rangoon and wants to marry Kamini, but is shattered as he finds out she is married to Raja. Raja's parents are told of the wedding and they call him home asking him to forget the marriage and marry a girl of their choice. Raja refuses and goes back to Kamini and misunderstands the situation when he sees Kamini with Sundar. He returns to his parents and tells them he's willing to marry the girl of their liking who turns out to be Rani, having returned from Colombo. Kamini, devastated by Raja's betrayal, decides to commit suicide. Finally with Kishore and Sundar's help, everything is sorted out and Raja is re-united with Kamini, while Kishore marries Rani.

Upperstall's reviewer Karan Bali wrote: "As with Bahar and many of her early films, it is Vyjayanthimala's dances that are the film's saving graces although it is unintentionally funny now to see how deliberate and obviously tacky the sequences are which lead into her dances Ladki too makes no real demands on 'feminist' tomboy Vyjayanthimala histrionically Kishore Kumar are strictly supportive appendages at best [...] Kishore Kumar does what he can, bringing the film to life with his lively antics whenever he is on screen. One sees his potential for zany comedy that would go on to flower fully in films like Aasha (1957), Chalti Ka Naam Gaadi (1958) and Half Ticket (1962)".^[1]

At the end of its theatrical run, the film grossed around ?1,50,00,000, and became the second highest grossing film of 1953 with a verdict of "hit".^[3]
