A bitter yet compliant African slave is killed for a crime he didn?t commit and is revived through black magic. Upon discovering he?s immortal, he?ll spend decades trying to recover what was stolen from him. New Logline: After a revived African slave discovers he is immortal after being framed for murder, he spends each passing century fighting bigotry to end how blacks are viewed in America. 5/3/2017

This latest draft is convoluted and a bit messy as it lacks a description of his action throughout the series. In Forever the MC is a medical examiner for the Police, and the action he pursues in each episode throughout the series is catching killers. In this logline you wrote he fights against racism against black people, why not change it so he fights bigotry – it’s not just black people who suffered from racism…
More so why not be more specific and write that he fights slavery? Slavery is the source of his pain so it would be fitting for him to want to stop it.

My suggestion:
After a revived slave discovers he is immortal on a slave traders ship, he spends each passing century fighting bigotry and abolish slavery around the world.

Great concept for a series, one that I’d like to hear more about (it’s rare for me to write such a comment on this site, as most members will attest…)

If you want more details on how to logline/pitch a series in general and episodes in particular, it would require more than I am able to in a thread response. So here are a few thoughts, this sounds like a logline that’s trying to describe the series as a whole instead of the pilot, for that reason I suggest making a few changes:

Beware of hinting at a premise pilot, describe the series as an ongoing affair after the start of his journey. In other words, make the logline describe him as an immortal with an agenda in the 19th century and onwards instead of a reincarnated slave in an earlier century.

I would also suggest you change the genre to supernatural instead of drama, his ability defines him and will provide the hook for most audiences. Like DPG said, time is on his side and not being able to die means he needs other big obstacles to overcome.
Perhaps there could also be an English officer, unbeknown to the MC, that was brought back to life who keeps chasing the MC throughout history?
Otherwise, the colour of his skin will provide him with many obstacles which can be exploited in the series.

The concept is very similar to the series Forever only instead of an English man it’s a slave that becomes immortal, for this to work the concept needs to be made different in the motivations driving the MC. Therefore, the logline needs to focus on the major obstacles he will have and his ongoing goal.
For example:
After a revived slave discovers he is immortal on a slave traders ship, he spends each passing century fighting bigotry in order to abolish slavery around the world.
