Detective work can be very difficult and demanding. However, sometimes those requirements can be very specific. Undercover work is part of detective work and it can also be demanding. All those things that happen in secret must be chased to the end, and if the identity of the detectives is revealed, it can change the course of the entire investigation, and even turn it in a different direction.
Detectives Betty and Paul are on a secret undercover mission in Venice. Apparently some American tourists were robbed by a gang of gondoliers. Gondoliers are supposed to be ambassadors, they're supposed to represent the city as their landmark, but it seems things can get out of hand sometimes.
They lure tourists with their gondolas and then take them to secret canals where they threaten to take away their valuables. This will be a difficult task as all the gondoliers are masked and it is difficult to reveal their identity.A way must be found to solve this problem once and for all.
