What We Do Is Secret is a 2007 American biographical film about Darby Crash, singer of the late-1970s Los Angeles punk rock band the Germs. It was directed by Rodger Grossman, who wrote the screenplay based on a story he had written with Michelle Baer Ghaffari, a friend of Crash's and co-producer of the film. Shane West stars as Crash, while Rick Gonzalez, Bijou Phillips, and Noah Segan respectively portray Germs members Pat Smear, Lorna Doom, and Don Bolles. The film follows the formation and career of the Germs, focusing on Crash's mysterious "five-year plan", his homosexual relationship with Rob Henley, and his experimentation with heroin, culminating in his December 1980 suicide. It is titled after the first track on the Germs' 1979 album (GI).

The Germs were an American punk rock band from Los Angeles, California, originally active from 1976 to 1980. The band's "classic" lineup consisted of singer Darby Crash, guitarist Pat Smear, bassist Lorna Doom and drummer Don Bolles. They released only one album, 1979's (GI), produced by Joan Jett, and were featured in Penelope Spheeris' seminal documentary film The Decline of Western Civilization, which chronicled the Los Angeles punk movement. The Germs disbanded following Crash's suicide in 1980. Their music was influential to many later rock acts, and Smear went on to achieve greater fame performing with Nirvana and Foo Fighters.
