Substitute teacher Henry Barthes is called in for a one-month assignment, teaching English classes at a high school with many students performing at a low grade level.

Later that day, he witnesses more aggression, when the mother of a student who has been expelled for harassing teacher Sarah Madison confronts her.

After school, Henry is called in to the care facility to see his grandfather who is suffering from dementia, as he has locked himself in the bathroom and will not come out.

On the bus ride home, Henry sees young sex worker Erica get hit by a man who refuses to pay her.

Later, a speaker gives a talk to the faculty, discussing how the low test scores are bringing down real estate prices, outraging the exhausted teachers.

However, Henry believes that Erica is showing responsibility, since she went grocery shopping and prepared dinner, which pleases him.

However, becoming so horrified by even the mention of committing such acts himself, Henry panics and is overcome by memories of his mother and grandfather.

Feeling on-edge after all that's happened, Henry informs Erica he can no longer take care of her, and has social services take her to a foster home.

On his last day of teaching, Henry reads to the class The Fall of the House of Usher by Edgar Allan Poe.

I used that to its full, here, to try and make sense of it all....[3] There's more [footage] of Marcia Gay Harden and Bryan Cranston [which] I've got in the hard drives, and I'm hoping to [get] it out, in maybe a longer cut."

The website's critics consensus reads: "Detachment's heart is in the right place, but overall it doesn't offer any solutions to its passionate ranting.
