After the death of his parents, Dan is left in the care of his grandmother who, although she wanted to continue instilling these values in him, was the only person who had shown him any affection throughout those gray years. When Dan enters the University, he meets Lucas, with whom he inadvertently falls madly in love. However, the fear that his grandmother might find out about his reality leads him to totally hide the relationship they both started. After the outbreak of the Apocalypse and the zombies taking over the streets, Dan and Lucas have to continue hiding to be able to see each other, being aware that they are risking their lives in each of their encounters until something happens that will change everything forever.
