Black Horizon, or Noir Horizon, is a french sci-fi comic. In the first issue, a group of convicts are sent through a kind of "black hole" portal that appeared to explore the other side, in exchange for their freedom. They land on a foreign planet, maybe a foreign dimension, and a strange, potentially living fog, transformed most of them into monsters.
4 survivors came back, and despite the promises, none of the get freed. One of the 4, a lady, gets "delivered" to a worehouse as a "reward".
