An all-girl rock band called the Dead Girls have made a name for themselves by recording songs which glorify death—at least until lead singer Bertha Beirut learns that her younger sister has been hospitalized following a group suicide pact inspired by one of her songs. Reeling from the shock, the band decides to put their tour on hiatus and convene at a remote cabin to reconsider the messages conveyed by their music. But when an uninvited guest shows up and begins to hack, chop, a strangle his way through the property, there soon might not be enough of a band to go back on the road!
