A small plane has to face the perils of delivering the mail over the treacherous Chilean Andes.
Pedro involves the title character, a small red anthropomorphic airplane from an airport near Santiago, Chile, engaging in his very first flight to pick up air mail from Mendoza, Argentina, with disastrous and treacherous results occurring when near Aconcagua again while chasing a vulture on the way back. And to make matters worse, Pedro gets caught in a terrible storm! But he makes it back to the airfield safe and sound with the mail which is just a postcard.
- Disappointed with Pedro as the image that the outside world had of Chile, cartoonist René Ríos Boettiger (Pepo) started one of the most famous Latin American comic magazines: Condorito.
