Brave and Bold (1918)

Robert Booth travels to Pittsburgh both to negotiate a million-dollar war contract with a foreign prince and to marry his sweetheart Ruth Hunneywell. Robert's rival Chester Firkins hires thugs to kidnap Robert so that he can win the contract for himself. Robert, however, escapes from the kidnappers, and after a series of adventures, during which he is pursued by the police and nearly blown up by a stick of dynamite, the daring Robert rescues Ruth, saves the prince's life and obtains the prized contract.
