In the aftermath of battle, a pair of Roundhead deserters come across an otherworldly young woman deep in the English countryside. Taking her for a witch, they force her into a derelict barn for interrogation - known as the 'search'. But as one deserter's paranoia and animal instincts take over, the situation swiftly spirals out of control, setting each protagonist against the others. As this twisting tale of the unexpected descends into dark violence, it becomes apparent that nothing is what it seems, and no-one who they claim to be.
