Insomnia has claimed everyone Biggs knows. Even his beloved wife, Carolyn, succumbed before disappearing into the quickly collapsing world. Yet Biggs can still sleep, and dream, so he sets out to find her. He ventures out into a world ransacked by mass confusion and desperation, where he meets others struggling against the tide of sleeplessness. Chase and Jordan are devising a scheme to live off their drug-store lootings; Lila is a high school student wandering the streets in an owl mask; Felicia abandons the sanctuary of a sleep research center to try to protect her family and perhaps reunite with Chase, an ex-boyfriend. However, Biggs persists in his quest for Carolyn, finding a resolve and inner strength that he never knew he had.
