The Search begins in Venice. Starting in St Mark's Square, the contestants must discover a lost map in the Arsenale di Venezia, Venice's military base. But can the 10 brilliant minds solve the most basic of treasure hunting skills and read a map?
The group's next stop is Florence, where they search for da Vinci's perfect circle. The hunt ends with the two teams of contestants racing to find the symbol hidden in the Leaning Tower of Pisa.
The winners will survive The Search for another week but the losers must play the Poisoned Chalice and eliminate one of their own.
