Parallel Lines

Is willingness ever enough?

Minhyun finds himself wrestling with the thought for years before an unsuspecting subway ride forces an answer out of him. Trapped with seven strangers, Minhyun and the other passengers are locked in individual coaches respectively where they need to enter a specific passcode to cross to the next coach.

Haunted by his spectres as a leader, Minhyun is reluctant to take up the mantle once again. Having his intentions and integrity questioned in their race against time is something he'd expected. And it wouldn't have mattered, except the person on the last coach is his brother, Dane.

Will everyone live to see the finish line or is death waiting at their final destination?
