Not sure if this is a spoiler, but in this remake of John Wyndham's book, the sap of Triffids is a source of energy-rich 'Triff-Oil' which solves the worldwide energy crisis and burns so cleanly it reverses global warming, even though the Triffids are carnivorous mobile plants with deadly stingers. Not a big problem until the world is struck blind and people become easy prey to the triffids. But here's my WTF moment: If Triffid sap is so flammable, why doesn't anybody use a torch on them? Or Napalm from an airplane? There must be at least ONE pilot who wasn't flying when the world went blind. All we ask is a little internal logic.
