Mission 4: Mexico

After the events of the previous mission in this adrenaline-fuelled global adventure series, rivalries are at boiling point. So, the scene is set for a shoot-out. The five remaining pairs must compete face-to-face. Their weapons are duelling pistols, the target a shot glass of tequila. Succeed and they bank £100,000 but two must fight for survival in an epic gladiatorial contest.
