These comments are based on watching the first three seasons but don’t give major plot details beyond the opening few episodes.
Marty Byrde is a successful Chicago financial adviser… whose most important client just happens to be a powerful Mexican drug cartel. When his business partner syphons off some of the money it looks like the end for Marty. His partner is killed but Marty manages to persuade the cartel to spare him by telling of a new plan to launder money. At this point he has no idea how he will do it but if he is to survive he, his wife Wendy and teenage children Charlotte and Jonah will have to move to the shore of the Lake of the Ozarks in Missouri. Once there he faces numerous difficulties; finding businesses to invest in; dealing with local criminals and the Kansas City Mob; and what happens when his children learn how their parents make their money. Over the course of the first three seasons they will face many dangers and not everybody who seems important to the story will survive.
