It's only a trip...it's only a trip, the American teens in this trippy terror flick keep telling themselves, after traveling to Ireland and taking (against a knowledgeable Irish friend's advice) some locally sprouting mushrooms. The stoned adolescents can't tell if the ghosts haunting their every move are just part of their hallucinations...or horrifyingly real. Lindsey Haun, Jack Huston, Maya Hazen star. 84 min. Soundtrack: English; Subtitles: Spanish.
