Summer camp at Rim of the World has barely begun when four misfit teenagers--Alex, ZhenZhen, Dariush, and Gabriel--find they've got bigger problems to face than learning how to canoe and climb ropes: aliens suddenly invade the planet. Alone in a campground once teeming with people, the kids are unexpectedly entrusted with a key that carries the secret to stopping the invasion. With no adults or electronics to help guide the way, it's clear what they must do: band together, conquer their fears, and save the world.—Netflix
