Shun used to work under Liao but vanished without a trace three years ago. Now, he's back seeking a job, despite being wanted by the police. Unlike the talkative Liao, Shun is quiet and mysterious, never mentioning his past, and Liao doesn't ask. Still, Liao senses Shun's desperation. On the heavily regulated construction site, Liao helps Shun navigate the heavily guarded construction site. Just as Shun gets through the checkpoints, the police arrive, catching both men off by surprise.
