Green Room (2015)

Maeby and her destitute Fugazi-loving D.C. punk band are cruising around the pacific northwest looking for gigs and stealing gas.

A recently-fired radio host gets them a last-minute show near Portland, which turns out to be in a neo-nazi forest compound. They open their set with the Dead Kennedy's "Nazi Punks Fuck Off" in protest.

They pop into the green room after their set to pick up a forgotten phone, and discover a group of neo-nazis huddled around a dead lady with a knife in her brain.

The surprisingly level-headed club manager gently persuades the band to be his hostages while he calls the cops and leads them away with a distraction. The distraction is a lesser stabbing.

Maeby & company realize they probably aren't getting out of this unhurt. They can't get out of the green room, but they manage to disarm a neo-nazi and take him hostage.

The club owner, a calm, quiet, and disappointed Patrick Stewart, arrives and takes over the negotiations. It goes pretty well until he hacks off one of the band members' hands, which sets the negotiations back a smidge.

The rest of the film is the band surging out, gaining ground bit-by-bit, and getting various appendages severed bit-by-bit. They timidly proffer a little heroin-based plot justification between scenes, but wisely choose not to linger on it.

The wise Sir Stewart leaves a mere two neo-nazis with a handful of shells to deal with the last two remaining band members, which is neither enough nazis nor shells, allowing the band to reach the Oregon wild and pop a hole in Stewart's skull.
