Swinging playboy Grand Duke Nicholas Goduno, a direct descendent of the Romanov family who were overthrown in the Russian Revolution of 1917, learns that his family's crown jewels will be exhibited at a London museum and plots to steal them. To this end, he gathers a crew of beautiful but dangerous women, led by Bridget Rafferty, to assist in his plot against Popov, the Soviet functionary in charge of the exhibit.
Unfortunately the movie Diamonds for Breakfast is not yet available on HBO Max.
