Eight colleagues are fishing on a mountain lake. Among them, Mehdi and Gilles drift away on a boat. Mehdi takes advantage of the moment to open up. He knows that several job cuts are planned.
Then one of their colleagues falls into the water and doesn't resurface. A second one also disappears. Something is trying to drag them down to the depths. Mehdi and Gilles will do everything they can to reach dry land. But the lake is against them.
