Plot
Two women living at different time zones are connected by a phone.
When 28-year-old Seo-yeon loses her cell phone on her way to visit her sick, estranged mother in a rural area. She digs up a decades-old cordless phone from the junk closet of her childhood home. Suddenly, she gets a call from a woman named Young-sook asking for her friend. Seo-yeon hangs up thinking the woman has the wrong number, but later learns that the call was coming from the same house 20 years ago.
