Allergic...TO BEES!
No-one has ever made a heart-stopping thriller called Allergic to Bees, but it could really be something. A guy living out his life just like everyone else, but just that little bit more carefully. Every few minutes he would see something yellow or black or yellow and black, or hear a buzzing, and for a second he'd go "Is that a bee?"
and then a minute later he'd go "Oh... no. I guess it's not a bee."
And then he'd move on.
It would be like Repulsion, with bees! Or no bees.
