OP-GHO, the follow up to OP-DEC, brings Carsten Reiniger back to audiences. After returning from Germany with Claire Healey and her aunt to New York City and a new life, his relationship with the girl has gone a few steps farther. Prepared to leave his bachelor days behind him, he works out the perfect time to ask her to marry him, but the moment is interrupted by a bomb. New York is home to a gregarious Nazi spy ring and they’re seeking help from the IRA to sabotage American installations. Claire is not so convinced that he’s left his spying days behind, and clues start popping up to insist that Carsten is still working for the Nazis.
