A King of Gangland vigilante takes on a tough young recruit but the AWOL commando desires his mentor’s bloody crown.

King of Gnagland vigilante seems like two very different archtypes. If you are a crime boss, you of course operate outside the law (thus a tautology). What makes him a vigilante? But at least with this logline (in contrast to the other two) you have got the central conflict that will drive the film clearly outlined.
