The wedding takes place with all the pomp and circumstance expected by all but the wedding night is less impressive as "Bluebeard" falls asleep, failing to honor his young wife. And just guess what the blushing bride does the next morning? She of course goes to the secret room to know everything about the secret beyond the door. But what she sees once the door is opened with the mysterious golden key has nothing to do with the legend...
