New mom Gabby Sutton would give anything - her promotion at work, millions of hard-earned travel points, her last shred of dignity - for a few uninterrupted hours of sleep. She just needs a break from the endless cycle of nursing, burping, and changing diapers. But telling herself she's got this isn't cutting it anymore, because (spoiler alert) she doesn't. That all changes one night when she observes a young couple from neighbouring houses get swept up in a secret rooftop rendezvous. Donning a pair of binoculars, Gabby starts tuning in to all her neighbours. Until a teenage girl goes missing. Confronted with the possibility that something sinister is going on in her sliver of suburbia, Gabby must contend with the possibility that one of her neighbours is hiding something - and might even be a killer.
