The game is set during a Venetian carnival, in a romantic age of spies, microfilms, hot-air balloons and fast speed-boats. As a secret agent, you will have to collect clues, use your deduction skills to recognize your friends and confound your foes, and find out what is the secret mission that will give victory to your team.

Players play in teams, but do not know who is a friend and who is an enemy. To win, you need to be able to figure out who your partner is, and exchange with him or her the secret code indicating your mission, before your opponents manage to do the same.
