When exiled from his town, a duplicitous man must confront his identity.

Sounds cool but you could add some stakes and a clearer goal to make it easier to visualize :)

1. More character information. Can't picture or realise simply a duplicitous man. Give him more substance and uniqueness.
2. Needs a more developed conflict
3. Higher stakes
4. Needs tangible action
5. There's no plot here - got to be a series of events the protagonist must overcome in order to achieve their...
6. GOAL - no goal clear here.

Despite sticking to the correct formula for writing a logline, the substance and interest and uniqueness is obviously lacking. Come back with a more developed story, character and conflict.

Just curious, where and when does this take place, obviously?it is not modern day America or Australia, I am curious if this is a fantasy setting or takes place in the past.
