After returning from Mexico, Stiles is confronted with the real reality of his actions and finds himself slowly transforming into something else. The ever-brooding Derek is the only one who seems to understand, and with townsfolk and hunters dying at an alarming rate, it's up to the newly-returned alpha, and the evolving-wit master to find, and stop the killers.
