After finally getting their new BDSM inn open, Brian and Kate travel to Europe for a well-deserved vacation and to meet Kate's family. On the flight over, Kate finds herself seated next to a passenger that leads them into a huge conspiracy involving the Catholic church on both sides of the pond. Kate does her best to keep Brian in the dark so he can enjoy their vacation, enlisting a local papperrazzi as her agent to solve the crime.
Along the way from London, to Isle of Man, to their motorcycle trip through the Alps, Brian and Kate manage to find new friends and have sex in the most spectacular locations in Europe.
