After Jack encounters a near fatal accident when he got hit by a car one winter night, his father sends him to New York City to visit a mysterious doctor (Dr. Lyons) who specializes in death.

After an unusually brief meeting with Dr. Lyons, Jack returns to Grand Central Station to catch a train back home.

He decides that it would be a shame to leave NYC without sightseeing first and squeezes himself into a nearby tour group by some pillars.

She offers to give him a tour of Grand Central Station and take him to places only 'True Urban Explorers' would know of.

Euri shows him a secret door on the sixth track which leads to a bunch of stairs.
