A young woman 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.
