I found a better description
Violet, Klaus, and Sunny Baudelaire have been walking for miles for hours in the hinterlands, on the run from the police and residents of the Village of Fowl Devotees, due to being falsely accused of murdering "Count Olaf" (Jacques Snicket) at the end of the previous book. They have no money, are exhausted, hungry, thirsty, lost and confused about where they should go.
Fortunately, they eventually arrive at the Last Chance General Store, a convenience store in the middle of nowhere. There, they find a shopkeeper who offers them breakfast and lets them send a telegram from the store to Mr. Poe seeking help. Unfortunately, the shopkeeper's deliveryman comes in with a copy of The Daily Punctilio which claims the Baudelaires are murderers. They flee and spot a van with V.F.D. on the side. A bearded man welcomes them, lets them enter, and says they just finished getting gas and are about to get going.
Inside the van, the Baudelaires learn they were picked up by Volunteers Fighting Disease, a group of enthusiasts that visit Heimlich Hospital to increase the morale of patients but never offer anything physically helpful, like medicine. They believe that 'No News Is Good News' and therefore have never read The Daily Punctilio and don't recognize the Baudelaires. One of the members suggests the Baudelaires seek a Library of Records to find their V.F.D. The children ask them if they knew a Jacques because Volunteers Fighting Disease's initials are V.F.D. They tell the children that they don't know him and add that they don't know each other's real names, but only call each other brother and sister.
