The second half of "Teen Wolf" season 5 returns to MTV on January 5. Before the show comes back, this new trailer promises terrifying dangers for Scott and his "Teen Wolf" family.

Love, family, and friendship will be tested. Enemies must team up to face a legendary beast called "The Gevaudan." The "Teen Wolf" crew is literally going to hell and back this season, and it's only going to get more intense.

"Teen Wolf" stars Dylan O'Brien, Tyler Posey, Arden Cho, and returns to MTV Tuesday January 5, 2016 at 9/8C.
