ABC has released a 30-second mid-season trailer for the cult zombie series "The Walking Dead."

The first half of "The Walking Dead" season six ended with the majority of Rick's crew trying to escape a hoard of 'walkers' when the young boy Sam starts to whimper, drawing the zombies' attention. The trailer revisits this crucial moment and also reminds the audience of a new storyline - that of The Saviors, a gang run by the villain Negan (to be played by Jeffrey Dean Morgan) who capture another group of the series' principal characters.

"The Walking Dead" returns on February 14, 2016.
