A young girl can't live without her phone, literally. On her way to a party her battery is running low and she must find a charger before it's too late. Because if her phone dies, she dies.

Seo-Yeon is going about her life in South Korea, walking in the streets on her way somewhere, when she discovered a catastrophe about to happen: her phone is about to run out of battery power, and she's in the middle of a phone chat party.

Desperate to maintain her lifeline to her digital life -- which has become entangled with her own survival as a human being -- she roams the city, trying to find some kind of recharging station or area to charge her phone. But her small tasks turn into a strange journey into ultra-modernity, revealing just how tethered she is to her connection to it.
