Need to play catch-up with “Fear the Walking Dead”? AMC is giving viewers the opportunity to relive the start of the zombie apocalypse with an all day marathon on Sunday, Aug. 21.

“Fear the Walking Dead,” the companion series to “The Walking Dead,” returns to the network Sunday at 9 p.m. EDT after a three-month hiatus. The show left off with Daniel ( Rubén Blades ) dead and the group of survivors separated after the compound went up in flames. As we previously reported, the upcoming eighth episode will catch fans up with Nick (Frank Dillane), who is on his own after he decided to abandon his mother. Viewers will have a chance to see whether he’ll continue flourishing in the deadly new environment, or if his luck will finally run out.

The midseason finale will air prior to episode 8 at 7:59 p.m. EDT for those that want a refresher. If you’re a new viewer with an interest in seeing what everyone is talking about, then you can catch the pilot episode and more starting at 7 a.m. EDT.
