In a supermarket parking lot, a plastic bag floats in the air and ends up on a shore. Like a being with a soul, a shopping cart breaks the chain that ties it to the others and starts wandering on its own. We see it dive into the sea and re-emerge full of plastic litter. Then the cart’s adventure becomes a journey around the world: it visits a henhouse to free the hens, it brings refreshments to field workers, it stops a bunch of tractors from spraying pesticides on crops and releases a whale that was tangled in fish nets. This is when more carts join our hero. The bunch reach the Antarctica and, together, they re-join two ice sheets that were drifting apart. The spot ends with the return of the protagonist back ‘home’, to the supermarket, and with Coop’s campaign claim “Good shopping can change the world”.
