Plot Summary

Yono (58) is a father who is clueless. He has a son named Suryo (21) who has wandered far into the city. It's been a long time, but Suryo never called Yono, and Yono's phone was never answered. Yono went to the cell phone counter, because he thought that the reason Suryo never called him was because his phone was broken. Is that right? Or are there other facts that strain the father and son relationship?
