Editing Big List of RPG Plots (section)

== Missing Memories ==

One or more of the PCs wakes up with no memory of the recent past, and now they find themselves in some kind of trouble they don't understand. The PCs must find the reason for the memory lapse, and solve any problems they uncover in the meantime.
* The forgetful PCs voluntarily suppressed or erased the memories, and they find themselves undoing their own work.
* The entire party is temporarily amnesiac.
* The PCs drank too much alcohol last night, and now have a massive hangover.
