1) 13 episodes instead of 18.
2) Marginalize or exclude new "Not twin peaks characters".
3) Bring the colors to the original, golden filmic experience, simulating the fujifilm used in the first two seasons (and not the flat digital arrialexa used for the third).
4) Rescoring, using Soundtracks from the original show (Total music added: 2h.18m).
5) Not anymore "green glove", and so different killing of Bob.
6) Less digital old style Computer graphics.

The story is entirely a figment of the Polish prostitute ('Lost Girl') who removed the trauma of an abortion and is held prisoner by the guilt of a homicide which she feels responsible for (the wife of her lover). A sinking, a descent into hell (apparently) inevitable.
