The Broken Promise.

Ralahamy, a man of high status, dies leaving his family in debt after having squandered his fortune through extensive drinking and other vices. To get back into wealth, Ralahamy's widow Tackla pushes their daughter Ranjani to marry Victor, a wealthy older man with a child from an earlier marriage. In this process, Samson, Ranjani's boyfriend, who had tried extensively to get the family back into good graces going so far as to pay off their debts, is spurned. He then goes abroad to win a fortune. When Samson returns he learns of Ranjani's engagement to Victor and tries to reach her through letters. His letters are hidden from her however, and rumours spread that Samson is now a cripple. Ultimately the truth is revealed.
