A Kickstarter-exclusive Catalyst campaign.
From the campaign guide text:
“Rehabilitation” takes place in the American Midwest shortly after the demons’ arrived. Red Death still ravages humanity. After coming in contact with a plague victim, the players embark on a perilous cross-country journey. They head towards a distant prison, rumored to be the last bastion of human hope. This facility may be one of the few thriving human populations left and, more importantly, may have a cure for Red Death.
