Billy Pilgrim becomes unstuck in time, experiencing World War II, alien abduction, and his own death in non-linear chaos.

Complete Plot Summary

The story jumps around because Billy experiences time non-linearly. He's a bumbling soldier in World War II, survives the Dresden bombing that killed 135,000 civilians, gets abducted by aliens who teach him that all moments exist simultaneously, becomes a successful optometrist, gets in a plane crash that kills everyone but him, and eventually gets assassinated by someone he knew in the war. "So it goes" appears every time someone dies (106 times total). The Tralfamadorians show him that free will is an illusion—all moments already exist, you just can't see them all at once.

Major Themes in Slaughterhouse-Five

Non-linear structure mirrors PTSD. "So it goes" after each death flattens mortality into mundane repetition. War is presented as absurd and incomprehensible rather than heroic. Free will versus determinism questions whether we control our lives. Dresden firebombing represents war's senseless civilian destruction. The bird call "poo-tee-weet" represents inadequacy of language after witnessing mass death.

The Ending Explained

Billy knows exactly when and how he'll die but can't prevent it. The book ends not with Billy's death but with the birds singing after the Dresden bombing—a moment of grace in the middle of the worst destruction he witnessed. Vonnegut's point? War is insane and beyond comprehension. Trying to make meaning from mass slaughter is impossible, so you end up saying "so it goes" because what else can you say? Time isn't linear—trauma makes you relive awful moments again and again. The Tralfamadorian philosophy (accepting you can't change anything) might be a coping mechanism for PTSD. It's an anti-war book that doesn't preach, it just shows the absurdity and horror and asks how anyone processes that level of death.
