A teaser trailer has been released for Marvel and Netflix's upcoming series The Defenders, which finally brings together Daredevil, Jessica Jones, Luke Cage, and Iron Fist. The teaser sees the group entering an elevator at Midland Financial Center, which was responsible for the large hole dug by The Hand in Daredevil season 2. AT the end, Jones punches the security camera and it stops at the time stamp 08:18:20:17. This is likely to indicate that the show will debut on August 18, 2017. Check out the teaser below.
