The Mystery of Line 11

The Mystery of Line 11 Plot:

Intern reporter Su Xiao infiltrates an old building beside the abandoned Line 11 tram route in the old town, chasing the "Mystery of Line 11"—the only clue left by her sister who disappeared three years ago. Lin Shen, the watchmaker at the building's ground floor, always wears a half-silver mask and listens to an old radio repeating Line 11's station announcements while repairing watches. Su Xiao discovers the flower-selling Aunt Wang has her sister's hairpin, Uncle Zhou cleans black stains on the tracks at midnight, and Lin Shen has her sister's notebook locked in his drawer—with the last page reading, "Beneath his mask lies Line 11's secret." When she follows the tracks to the abandoned station, her sister's graffiti on the wall—"Don't touch that radio"—catches her eye. Suddenly, Lin Shen appears: "I've waited longer for this day than you've searched for your sister."
