Meet Alex, a resourceful teenager with a knack for tinkering. When selected for the Hunger Games, he opts for an unusual item: a solar-powered portable water purifier. While it may seem unassuming, this device becomes his lifeline in the arena.

As the games progress, Alex cleverly uses the purifier to not only provide clean drinking water but also to camouflage his scent from predators, by purifying the water he uses for bathing. Additionally, he uses it to lure opponents by creating small oases, then ambushing them when they least expect it. With his inventive mind and the versatile purifier, Alex outwits his adversaries and emerges as an unexpected victor of the Hunger Games.
