DC’s Final Trailer has arrived just in time to get fans excited for its premiere on Friday. Swamp Thing plans to deliver a giant muck monster and a supernatural battle between the light and dark.
In the trailer, we see a town descend into chaos. Many citizens become inflicted with a disease that causes plant life to grow from their bodies. An investigation of the disease leads CDC investigator Abby Arcane (Crystal Reed) to a mysterious Louisiana swamp.
