Tara (Tara Jane O'Neil) is growing weary of her life at the Rocket House, a party pad filled with crashing slackers, artists, and rock bands. She works as a ticket taker at a movie theatre and hangs out with a group of friends who are equally aimless, skateboarding through the streets of Louisville, KY, and just generally waiting for their lives to start. Her brother, Otis (Ian Svenonius), is the arrogant lead singer of a local rock group called the Guilloteens, and one night after a gig, Tara and her pals steal the band's van (still full of equipment) and head off into the night. The next morning they find themselves in Chattanooga without money or food, so they pose as a touring rock band called Truckstop and talk their way onto the bill of a local punk show. Despite being utterly unfamiliar with the instruments in their hands, they pull off the ruse, and the band they play with loves their noisy, chaotic sound. Even after their secret is revealed, their hosts give them encouragement and tutoring to allow Truckstop to continue on the road. What starts as a romantic adventure, though, degenerates into bickering, bad luck, and boredom. Half-Cocked features members of indie bands like Retsin, the Make Up, Rachel's, and June of 44 as actors, plus an appearance by Memphis rockers the Grifters. The soundtrack includes music by Freakwater, Sleepyhead, Unwound, Smog, and others.
