I didn't know anything about ALL FLOWERS IN TIME... and now that I've seen the poster and synopsis I still don't.

 

Synopsis 

"I am not from this place," declares a French cowboy. An old toothless man asks, "Do you know why you're here?" These shape-shifting personalities infect young children with an evil signal in the form of a Dutch TV show. The red-eyed girls and boys believe they can now become other people and monsters, much to their delight. 

 

Thanks to TWITCH for this... I think
