Six strangers find themselves in circumstances beyond their control, and must use their wits to survive.

British documentarian Nick Broomfield creates a follow-up piece to his 1992 documentary of the serial killer Aileen Wuornos, a highway prostitute who was convicted of killing six men in Florida between 1989 and 1990. Interviewing an increasingly mentally unstable Wuornos, Broomfield captures the distorted mind of a murderer whom the state of Florida deems of sound mind -- and therefore fit to execute. Throughout the film, Broomfield includes footage of his testimony at Wuornos' trial.

War and Peace of Mind explores what war does to the human mind and how both, the individuals and the nation as a whole, survive it psychologically. Finland and WWII, locally known as continuation war, is the backdrop of this documentary.
