When law fails society and crimes go unpunished, there is only one option: vigilante justice. The wheels of justice spin a little quicker when one person assumes the roles of judge, jury, and executioner—but, unfortunately, that person is usually some psycho ex-soldier who loses his mind and goes on a murderous rampage. So it comes as little surprise that Charlie (Nick Panouzis, in his only credited acting role), the batshit crazy Vietnam vet hired by a right-wing watchdog group to clean up the streets in Peter Maris’ 1979 flick Delirium, strays from his mission and starts killing everyone he comes across. Of course, nothing springs lazy cops back into action than a little vigilantism, so—in between flashbacks—Charlie has to elude the two detectives hot on his bloody trail. Had the police been doing their job, poor Charlie never would have had to be contacted in the first place. Then again, such action would rob audiences of 90 minutes’ worth of violence, bad acting, and stock footage. The film shows at 8 p.m. at Dr. Dremo’s Taphouse, 2001 Clarendon Blvd., Arlington; sponsored by the Washington Psychotronic Film Society. Free. (202) 736-1732.
