Dr. Eva Graff and Brynn Emerson have barely survived their ordeal on the Vault when an even more dire complication rears its head. In order to save what's left of Fathom base, the two women must work together to stop a dark event from occurring on the abandoned Southern platform...but the events of the past day, including the reveal of Mack's true agenda, have taken their toll on Eva. She can't stop hearing the sounds of her daughter Alex, can't stop wondering whether they were real or just the hallucinations from intense radiation exposure. And as the situation becomes more and more desperate, she will question everything...and, eventually, choose her path. FATHOM is created, written and directed by J.
