The dawn of the 18th breaks and Nathan recalls that it was the date that the rescue team was due to come. Those zombie-like infected surrounding the house suddenly are all shot dead and everyone else seems safe. Nathan wanders outside the house and thanks the person or persons who saved his life. However, the soldier gets orders to leave no survivors. Nathan suddenly finds himself surrounded and then shot to death while Sharon and the now returned Jonah watch. When trying to escape, Sharon is stabbed in the back by an infected woman. With very few options available to them, Jonah decides that the only way to escape execution is if he and Sharon were to take the vaccine again, thus appearing to be dead until the soldiers disappear. They climb back into the pit of bodies from the beginning of the film and Sharon gives Jonah the letter she wrote earlier, telling him that he must remember. Jonah passes into unconsciousness and the letter falls from his grasp. When he awakens later, Sharon has now died from her wounds although Jonah doesn't know who she is. The mute throws down a rope to allow him to escape. As his memory recovers, he and the mute start a journey to an unknown location. It is revealed in the note that the mute is the source of a cure, as her blood is immune to the infection. Finally, Sharon states a message for Jonah "my love, I remembered everything, we were both doctors on the verge of finding a cure for an awful plague that cast the world into darkness, the mute woman is the answer, her blood is immune to the virus you must protect her, you will find death and madness everywhere, but you have to fight to finish what we have started. we have no time Jonah, there are still people waiting to be saved, I know your memory will come back soon, when it does remember I love you".
