The trailer, which debuted Friday during The Walking Dead's San Diego Comic-Con panel, shows Rick (played by Andrew Lincoln) explaining how far he and his band of survivors have come from when the undead started to attack humanity. 

It might look like a great pep talk, until you see he's chatting with the very dangerous murderer Negan (Jeffrey Dean Morgan), who is currently locked in a jail cell and will most likely try to kill Rick as soon as he escapes.
