Living in 2040 in an age of harsh austerity, Ethan Thomas works for a sinister organisation that enforces the 'Sleep Code' – laws which regulate sleep in order to fulfil the United Kingdom's need for economic growth. A strong belief in the justice of his work drives Ethan to fanatically pursue sleep criminals and his own lazy colleagues to the detriment of his personal relationships.
Ethan's conscientiousness leads his superiors to assign him to a new project where he will be responsible for identifying a group of subversives working to undermine the Sleep Code. Delving into a world of secretive intelligence agencies and groups with ambiguous loyalties, Ethan works night and day to fulfil his duty.
But when he develops a problematic sleep disorder, Ethan finds himself increasingly compromised personally and professionally. Experiencing the same situations that he has previously investigated, he witness the corrupt ways that the law is enforced. Now Ethan must decide whether he can maintain his integrity and his belief in the system he defends.
