Confidential Agent is a 1945 American spy film starring Charles Boyer and Lauren Bacall which was a Warner Brothers production.

In the midst of the Spanish Civil War, Luis Denard (Charles Boyer), a former concert pianist and composer, travels to England as a confidential agent of the Republican government.

On the ship, he meets bored rich girl Rose Cullen (Lauren Bacall), whose father, Lord Benditch (Holmes Herbert), heads the firm with which Denard will negotiate.

When he meets his contacts, Contreras (Peter Lorre) and Maria Melandez (Katina Paxinou), he finds they have sold out to the Fascists and want him discredited or killed.

Unable to buy any coal, Denard tries to persuade the miners to support their fellow workers in Spain, but they put work ahead of principle.
