A weak white supremacist falsely jailed for drugs, gets trained and helped escape by a racist black ex-cop inmate, to hunt down the bad guys and prove his innocence.

"When two inmates, a white supremacist and a black supremacist, learn they have been framed by the same chinese con artist, they team up to escape and get their brutal revenge, only to find he's far too smart for them".

Many thanks Bro.

As DPG mentioned the odd couple trope is what make this potentially appealing in my mind the story in it's own right doesn't.

The plot you described seems convoluted the events are seemingly random as the son by chance bumps into the MC and by chance plants the drugs on his person then by chance gets away. Then the mysterious drug lord bribes some unrelated people and by chance both cop and MC are arrested.

Up to this point the MC is passive the story happens around him and conveniently puts him in an odd couple situation with a black man. Admittedly this is all before the inciting incident of him getting arrested but he seams like a person that wants nothing, has no ambitions and is a racist. Will the audience care what happens to him or not but the time act one ends? I would endeavour to say no.

I suggest re thinking the specifics of the plot that brings the odd couple together and the type of their opposing natures. A recent example of such a dynamic is Get Hard with Will Ferrell, wash't a great film but very similar in character dynamic.

Hope this helps.
