A farewell party takes a deadly turn after a power cut plunges the gathering into darkness. When the lights return, one guest lies dead on the floor, a kitchen knife in his chest. Forced to investigate to clear his name, Dennis reconstructs the blackout second by second, exposing contradictions in the guests' stories and asking whether the killing was a sudden act of rage or meticulously planned.
