Mission 5: Day of the Dead (S02E06)

The Controller dispatches the last four pairs to Mexico City in pursuit of a key that could grant them a £250,000 reward. However, the Day of the Dead festivities bring a million jubilant partygoers into the mix, complicating their quest. To achieve success, the contestants must form alliances for the first time. With the spirits of the departed making their presence known, any misstep could result in a confrontation with a vengeful ghost.
