Quibi's WHEN THE STREETLIGHTS GO ON (2020): A High School Student-Teacher Sexual Affair Turns Deadly

Here's Quibi's plot summary for When The Streetlights Go On (2020): "A double-homicide in a small midwestern suburb rattles the lives of a group of teenagers and sends investigators searching for answers in the fall of 1995. A meditation on growing up, the passing of time, and the insidious violence that lurks in the suburbs."

Oddly, Quibi didn't mention the names or descriptions of the double-homicide victims.

IMDb has a shorter but slightly more descriptive plot summary: "The residents of a small town grapple with the ruthless killing of a young girl and a teacher."

That's better, but we'll add some vital details. The young girl is Chrissy Monroe and the [English] teacher is Mr. Carpenter - Chrissy's lover. Mr. Carpenter is described as: "[...] the teacher all the guys wanted to be and all the girls wanted to be with."

I won't spoil the ending by revealing the killer(s), but I'll remind you that, unsurprisingly, teen boys and middle-aged women are typically the most adverse to age-gap relationships between nymphets and men. 

[Update] Quibi is now defunct, but the shows are moving to the Roku channel.
