The trolley dilemma, where truth is elusive and contingent on perspective. Trolley is a slow burner which peels backs the many layers of truth and alters our own perception of it in the process. Chung Su-Bin gives an absolutely mesmerizing, magical performance as a young woman caught in the eye of a storm. A thoughtful, intelligent drama where nothing is quite what it appears to be on the surface . An unflinching and often devastating look at the consequences of the choices we make for the "greater good" .
