Marisol runs the last full-service tunnel wash on a dying highway strip, and she's built a side business nobody advertises: for four hundred dollars cash she'll take a car through with the cameras off, the drains rerouted to a barrel, and no receipt. Her clients are hunters with sloppy truck beds, roofers who hit something in the dark, and, increasingly, men who won't say. She has one rule — she never looks in the back seat — and one habit she can't quit: she keeps every barrel, labeled by date, stacked four high in the shed behind the vacuum bays.
The missing woman's mother hires her own lawyer and subpoenas the barrels, and Marisol, on the stand, finally admits why she kept them: she never intended to sell them or destroy them. She grew up with a brother who went into a car wash in 1994 and came out clean, and the search dogs found nothing, ever, because there was nothing left to find. The barrels aren't leverage and they aren't trophies — they're a lost and found. She has been keeping the evidence she was never given, for families she'll never meet, waiting for someone to finally come ask. Ninety-one barrels, ninety-one dates, and she can recite what kind of car was in the bay for every one of them.
💡 The engine is a service business whose product is erasure run by a woman whose entire life was ruined by an erasure — so every barrel she fills is simultaneously a crime and an act of archival grief, and the audience keeps recalculating which one it is.
