The Tripper (2006)

Teenagers don't know what it's like to worry. An open-air concert is being held in the Sequoia Forest somewhere, where young men and women get together to laugh and sing and get drunk. A group of hippies sneaked into the hinterland of the forest to hold a weekend carnival with heroin and marijuana as the theme. Their uproar woke up the old woman living in the forest, the woman in Reagan mask launched a bloody chase against the hippies. The film, one of the Dark Pictures'"eight horrible death movies" series, is rated R by MPAA for drugs, violence, blood type and other elements. The title Tripper is taken from the homonym of Reagan's nickname Gipper. The film was released on April 20, with 420 alluding to marijuana.
