Diamonds Adrift (1921)

Wealthy shipowner James Bellamy decides to punish his carefree son, Bob, by forcing him to pay his $5,000 in debts by working as a $50-a-month supercargo. In a card game, Bob wins a runaway Persian cat, which is wearing a $30,000 diamond bracelet. Not realizing their value, he gives both cat and bracelet to Consuela Velasco, a girl he meets in Mexico. Back in San Francisco, he learns the true value of the bracelet and returns to Mexico just as Consuela is about to marry against her will. Bob carries off the girl, cat, and bracelet; gets the reward; and is reconciled with his father.
