I find it good that a man who has little wealth but great knowledge has a noble cause to support his family with drug money but with many twists of being in a drug business.

Because it is a series I strongly recommend starting from episode 1 of season 1 if you decide to watch it.

yes, I have to start tv shows at episode 1

yeah, not everyone does it unfortunately. Those type of people are the ones who give badly written reviews when they don't understand parts of the shows.
