Let me introduce you to the TV show Industry which takes you into the world of London high finance where tense phone calls, compliance violations and financial crimes are the order of the day [1]
It's HBO. They are known for this. But they definitely went too far with Industry in my opinion.
The sex and drug scenes are much more toned down in the latter two seasons. Part of the reason why is the cast had more leverage and strong armed the writers / directors.
Great show but definitely would be better with 90% of the sex / drug scenes removed.
This is like medical series about ER, in real life it doesn't happen. In real life nobody cares, things slip trough, people die, finally someone receives a huge bill.
