Through real-time bodycam and phone footage, frontline activists take audiences along on their audacious raids to tear down arms factories around the UK, capturing the immediacy and urgency of direct action in defense of Palestine. The film humanises a covert movement, presenting trespass and property damage as moral resistance to complicity in conflict, forcing viewers to consider how they would behave if they were in the activists' shoes. By blending first-person archival footage with testimony from those activists and people close to them, To Kill a War Machine sheds light on the efforts of Palestine Action to dismantle companies supplying weapons to the ongoing genocide in Gaza, raising questions about complicity in conflict and the power of individual action.
