A 17th-century alchemist captures a small band of English Civil War deserters, and forces them to help him search for buried treasure in this psychedelic horror drama from director Ben Wheatley (Kill List, Sightseers). The year is 1648 A.D. As a fierce battle rages in the English countryside, a small group of soldiers flee for their lives. They're nearly free when they encounter the mysterious O'Neil (Michael Smiley), who guides them across a sprawling mushroom circle in search of an elusive treasure. After dining on the abundant fungi, the weary travelers experience a paranoid break from reality while suspecting that the treasure may not be gold, as they initially suspected. Meanwhile, mysterious forces in the field begin to stir. Reece Shearsmith and Julian Barratt co-star.
