Poolman (2023) on Netflix

Plot summary

Darren Barrenman cleans the pool at the Tahitian Tiki, an old Los Angeles apartment block owned by Jack and Diane. A native Angeleno who admires Erin Brockovich, he keeps pitching the city council on improvements, to councillor Stephen Toronkowski's disdain. His girlfriend Susan, tired of his causes and his reluctance to move their relationship forward, leaves him. June Del Rey then tells him her boss, Toronkowski, takes bribes and is tied to a property developer, and asks for his help. He turns her down at first, takes a psychiatric session with Diane, and then agrees to meet June at an expensive club, where she says she has no idea how far the corruption reaches. He begins gathering friends and neighbors to track the councillor and photograph his misdeeds.
