Rim of the World is a 2019 American science fiction adventure film directed by McG and written by Zack Stentz.
[5] Alex, a socially reclusive boy who recently lost his father in a fire, reluctantly attends a summer camp in southern California called "Rim of the World".
Dariush mistakenly tries to 'cure' Alex's fear of heights by making him stand near a cliff edge, and Gabriel, a boy they hadn't seen at camp before, intervenes.
The dying astronaut inside the spacecraft gives Alex a key, with instructions that it should be taken to NASA's Jet Propulsion Lab (JPL) facility in Pasadena, and that it is the only way to destroy the aliens.
However, alien ships attack the vehicle convoy and the soldiers are killed, whereupon Alex retrieves the key from the dying commander and the group sets out for JPL once more.
Suddenly, they receive on their transmitter an SOS from the doctor at JPL they were instructed to give the key to, encouraging them to move forward with their journey.
The group finally make it to the JPL facility, but find that the doctor is dead, and his SOS message was only a result of his blood dripping onto his transmitter.
The kids are able to make radio contact with a general at NORAD, who explains that the key holds information that can be used to destroy the alien mothership in orbit via a Cold War defense project named Excalibur.
The website's critical consensus reads, "Rim of the World is too bland to live up to the 80s teen adventures it references, and too full of clichés to be able to set itself apart from them.
