Contents: Chosen Underling villain (see rulebook p. 5). Chosen villain's set, The Raft Breakout set, and Standard set. Two modular encounter sets (The Owl and Tombstone).

Setup: Attach Master Key to the villain. Each player discards cards from the encounter deck until they discard a Prisoner minion and reveal that minion.

Each minion gains: "When Defeated: Remove 1 threat from the main scheme (2 threat instead if this minion has the Elite trait)."

If this stage is completed, the players lose the game.
