The Encyclopedia Of Indian Cinema says this about Chori Chori:

A lively comedy derived from Capra’s It Happened One Night (1934). A millionaire’s daughter affectionately nicknamed Baby (Nargis) wants to marry a man her father knows to be a gold-digger. Annoyed by her father, she runs away and meets the impoverished journalist Suman (Kapoor). Together they journey through South India and they fall in love. This is the last of the romantic duos between Nargis and Kapoor. Nargis only appeared once more in his films: Jagte Raho (1956) as a final tribute to her collaboration with RK Films.
