AMC has released a trailer and clip for the mid-season finale of The Walking Dead, called "Too Far Gone." It's been described as follows,
After things begin to calm at the prison, Rick and the group face imminent danger.
The trailer below will give you a good look at what that imminent danger will entail. I've enjoyed seeing the Governor back on the series, and seeing his journey back into power and murdering madness. It looks like we're in for one hell of an intense mid-season finale!
