'Teen Wolf's' Season 5 Trailer Warns 'They're Coming For All of Us'

The foreboding new trailer for "Teen Wolf's" fifth season leaves little doubt that life is about to turn "really bad" in Beacon Hill.

"They're coming," a voice says, seemingly referring to the steampunk-ish, maybe even mechanical, "doctors." "They're coming for all of us."

There's also the introduction of the Theo (Cody Christian), a mysterious lone wolf who seeks to join Scott's (Tyler Posey) pack, Lydia's stay at Eichorn House, and hints of an upturning of the supernatural order and the figure behind it.

Also starring Dylan O'Brien, Holland Roden, Shelley Hennig, Arden Cho and Dylan Sprayberry, "Teen Wolf" returns Monday, June 29, at 10 p.m. ET/PT on MTV.
