Manchali (1973)

One condition prevents young Leena (Leena Chandravarkar) from receiving her inheritance: She's unwed -- and until she marries, her uncle won't relinquish her legacy. When the frustrated Leena meets jobless Sanjeev (Sanjeev Kumar), the duo concocts a quid-pro-quo scheme: For a sum, Sanjeev will temporarily pose as her spouse. But once Leena has her fortune in hand, she's ready for "hubby" to make tracks.
