María needs 3 million pesetas to expand her farm, and Gonzalo is offered a lucrative business if he can invest 30 million pesetas, but they don't have that much liquidity. Don Leopoldo had offered himself as their slave to have food and shelter as he was almost evicted. Suddenly Don Leopoldo ears 33 million pesetas in late royalties, and he insists that money belongs to Gonzalo and María. Gonzalo and María are tempted, but reluctant to spend Don Leopoldo's money. In the end, they only allow Don Leopoldo to usufruct the 33 million pesetas, then release Don Leopoldo; but the audience does not know what will happen with the money.
