You are a scientist, specifically in the field of biology. As soon as you finished your university degree, you were selected to work for the US government, on a secret project. When you arrive at your new job, you are introduced to the objective you have to study, "subject 001", the only one of his species captured within the facilities, is a Yautj'a.

(you can follow the plot however you want, you can make this a romance or a friendship, I don't know, that's up to you. :P)
