A bright-eyed corporate spy (Brit Marling, who also co-wrote the script) infiltrates the title eco-terrorist group run by a charismatic Alexander Skarsgård and his zealous right-hand woman, Ellen Page. Aiming to stop them, Marling finds her loyalties torn after she takes part in subversive attacks on unethical corporations. Marling and her co-writer, director Zal Batmanglij, deliver gripping suspense and challenging ideas in this thought-provoking political thriller. Marling is excellent and gets fine support from Skarsgård, Page and Patricia Clarkson, as her coolly cynical boss.
