Remove each Cave location from the game (discarding all enemies, tokens, and attachments at those locations). If River Hawthorne is in play but not under control of any investigator, remove them from the game.

Each investigator loses all but 2 of their clues.

If it is agenda 1a, advance the agenda directly to agenda 2a (do not resolve agenda 1b).

Your search for supplies will help you navigate whatever is ahead. Flip the scenario reference card over to its other side, moving all scraps on it to that side, as switches.
