Sara is returning home from a conference abroad when agents from the Risk Assessment Administration pull her aside at the airport and inform her that she will commit a crime.
Using data from her dreams, their algorithm has determined that she presents an imminent risk to the person she loves most, and must now be transferred to a retention centre for twenty-one days to lower her 'risk score'.
But when Sara arrives at Madison to be observed alongside other dangerous dreamers, it soon becomes clear that getting home to her family is going to cost more than just three weeks of good behaviour. And as every minor misdemeanour, every slight deviation from the rules, adds time to her stay, she begins to wonder if there might be more here than first meets the eye.
Then, one day, a new resident arrives, disrupting the order of the facility and setting off a chain of events that lead Sara on a collision course with the companies that have deprived her of her freedom.
