"Wen" (Kristen Cui) is out collecting grasshoppers when she encounters the statuesque and friendly "Leonard" (Dave Bautista). When his three friends turn up though, she gets spooked and runs to her remote cabin home where her dads "Eric" (Jonathan Groff) and "Andrew" (Ben Aldridge) are chilling on the veranda. She is worried, and soon they are locked in with four seemingly hostile folks outside demanding entry. The doors and windows are no match for their rather medieval weapons and soon the boys are tied to their chairs fearing the worst in homophobic behaviour. Thing is, the four appear to mean them no harm - well, not directly anyway. "Leonard", in a calm and measured manner, now regales them with a tale foretelling an apocalyptic end for mankind unless this small family make a very, very, tough decision in the next twenty four hours. Should they not, then we soon discover that things will not go well for them, but do not go at all well for their four "persuaders" either. Bautista is quite good here, as is Aldridge and for a while the plot is actually quite intriguing. The ultimate catch-22 with a question posed to rational people - who love each other - that would test any of us. Sadly, though, M Night Shyamalan can't keep the intrigue sustained and it rather runs out of steam from the middle onwards. Groff doesn't really show up and neither, for that matter, does Rupert Grint. I also felt that young Cui takes a little too much screen time and grates after a while. It's the shortest of short stories, and might have worked better had it just been the hour with a tighter narrative and less meandering. Still - it does ask a question that I'm not sure I could answer either in their position - and I did quite enjoy watching it.
