在这部三尖树时代恐怖/科幻片中,绰号三脚妖的这种植物是经过基因改造的人工植物，长着可怕的毒刺，并且拥有和动物类似的敏锐感官，以及三只可以移动的 "脚"。在这个故事里，人们为了获取它们身上的油（汁液）而大量种植它们。一场诡异的流星雨用不可思议的亮度照亮了全球，绝大多数人类的眼睛在瞬间变瞎了。三脚妖于是乘人类虚弱之际发动 "叛乱"，可怜的人类因为看不见东西，竟毫无还手之力。该故事于1962年被拍成电影，1981年被BBC拍成电视剧，2009年将再次被BBC拍成电视剧。
A shower of meteorites produces a glow that blinds anyone that looks at it. As it was such a beautiful sight, most people were watching, and as a consequence, 99% of the population go blind. In the original novel, this chaos results in the escape of some Triffids: experimental plants that are capable of moving themselves around and attacking people. In the film version, however, the Triffids are not experimental plants. Instead they are space aliens whose spores have arrived in an earlier meteor shower.
植物版的丧尸片。
