Christmas, Hawkins, 1984. All Chief Jim Hopper wants is to enjoy a quiet first Christmas with Eleven, but his adopted daughter has other plans. Over Hopper's protests, she pulls a cardboard box marked "New York" out of the basement-- and the tough questions begin. Summer, New York City, 1977. Hopper is starting over after returning home from Vietnam. A young daughter, a caring wife, and a new beat as an NYPD detective make it easy to slip back into life as a civilian. But after shadowy federal agents suddenly show up and seize the files about a series of brutal, unsolved murders, Hopper takes matters into his own hands, risking everything to discover the truth. -- adapted from jacket
