The United Nations is on a mission to tackle air pollution, with the help of parkour artist Georgia Munroe.
The short series shows Munroe as she attempts to escape from a bright purple cloud of air pollution.
"You can run, but you can’t hide," the ad declares, giving viewers the option to choose how the story ends. While one ending sees the parkour pro scream into the fog, forcing it to retreat, another shows her as she falls victim to the purple haze, which is decidedly less appealing than Jimi Hendrix once suggested. It was created by Ben Polkinghorne and Scott Kelly, and directed by Rubika Shah through Grain Media
