Disillusioned government worker, Ryan, is stuck in a soulless job at the local town council. While tracking down a missing recycling bin, he encounters a homeless man, Peng, who claims to be an extraterrestrial. As Ryan begrudgingly teams up with Peng to hunt for the latter's doomsday device, they embark on a madcap adventure through Singapore: running into a rabid doomsday cult hot on their heels, dodging top-secret government agents, yet finding surprising allies who join their cause.

Sometimes by simply helping the person next to you — even if they are a crazy-looking homeless man who's really an alien — you can Save The World!!!
