Lasanda is the name of the girl played by the famous actress Nita Fernando. Her acting amplifies the moral qualities of her heroine – a proud woman, irreconcilable to everything that degrades human dignity. The world is divided into two clearly delineated camps. In one of them are the rich mine owners and their accomplices, in the other - the working class, the poor, forced to make ends meet with odd jobs.

The second are almost powerless in the face of tyranny and violence; their existence, their future depend on the whim of their masters.
