It’s 1985 in Hawkins, and Y/N Harrington, Steve’s younger sister, is popular but used to living in his shadow. Lately, Steve has been acting less of a jerk, strange and secretive, leaving Y/N curious and slightly worried. When she visits Family Video for the first time, she meets Robin Buckley, witty and sharp, sparking an unexpected connection. At school, Y/N works as a photographer for the school journal and encounters Nancy Wheeler, Steve’s ex, whose presence brings both tension and intrigue.
