He and his friend Harvey are invited by their old friend Clark to go to a nightclub with three aristocratic Russians on their last night. Ogden drinks too much and spends the night with Countess Natascha. The next morning, while sailing back home, Ogden finds Natascha hidden in his cabin wearing a ball gown and with no documents. The stowaway explains that she wants to go to the United States and Ogden is worried about his career. But Harvey convinces him to help Natascha. Ogden falls in love with Natascha, and he and Harvey plot a fake marriage between Natascha and his valet Hudson. Things get complicated when Immigration requests Natascha's documents and Martha arrives on board.
