Detective Dave Strauss is happily married to Susan Bailey, owner of a chocolate shop nestled in the gentrifying industrial neighborhood of DUMBO, Brooklyn. Susan's younger sister, fourteen-year-old Lisa, lives with them. When Susan is forced to reveal a long-held family secret, Lisa bolts and doesn't return. Assuming she has run away, Dave and Susan search the shadowy cobbled streets beneath the Brooklyn Bridge, but Lisa is nowhere to be found. Soon clues gather to suggest the stark probability that Dave's old nemesis has returned to torment him.
Over the course of one long, cold night, Susan struggles to hold onto her marriage as her faith in old decisions crumbles, while Dave relives the unsolved case of a girl who left her middle school one day and never arrived home. His worst fear is that the two cases are connected and he will fail to find Lisa, as well.
As the hours pass and the night grows darker, with only a trail of blood and a series of untraceable phone calls from ''the groom'' hinting at Lisa's fate, Dave and Susan know that her disappearance is not a tragic coincidence...and that they have limited time to find her before she vanishes completely.
