When his only friend goes missing under mysterious circumstances, a suicidally depressed teenager tries to become a masked vigilante in order to find him.

A vigilante is someone who takes it upon himself to punish someone else being a criminal.? But the logline says? his friend died under mysterious circumstances.? So how can he be a vigilante if the circumstances are mysterious, if he doesn’t even know his friend’s final fate or who is responsible?? Wouldn’t it be more accurate to say the teen becomes his own private investigator?? In which case, why does he need to wear a mask?
