There are complicated motives at play in this series, no matter what path you choose through the story. It's got a murder, and then a bunch of people who were all motivated to do it by their desires for money, power, real estate.
Violence is sporadic, but may be upsetting to younger viewers: A family in a swamp boat in Louisiana shoots an alligator, repeatedly referring to it as a "trophy," we see a (fake) gator get shot, without blood; a moment later, we see meat being tucked into a cooler. During an argument a man punches a wall repeatedly, yelling "f--k!" A woman is murdered, but what we see is her studio with a small puddle of blood and a body with a close-up on a decomposed hand with rings in a creek.
Expect flirting, dating; a woman refers to asking a man to come in (presumably for sex) and says if she doesn't the "night will last longer." A woman flirting with a bartender says she wants a drink that's "tall and muscular," and then whispers that she didn't mention "stiff."
Cursing includes "f--k," "s--t," "a--hole," "ass," "hell," "goddammit," "damn," "Jesus Christ." A woman shoots a man the bird in jest. One man calls another "moron."
We see the end of a joint next to a lighter in an ashtray; adults drink wine at dinner; one refers to having had a glass or two too many, and acts a little sloppy. When he's upset, a man says "I need a drink."
