Part 4/11:
With the group divided and a terrifying onslaught of zombies crashing their refuge, Alice's maternal instincts lead her to search for the boy amidst the turmoil, only to be separated from Don. He grapples with indecision, torn between loyalty to his wife and the instinct for self-preservation, ultimately escaping through the window as he witnesses the horrific transformation of his once-loving spouse into a ravenous monster.
The aftermath leaves him emotionally shattered and alone, battling against the zombie onslaught and making his way to a motorboat, where salvation appears momentarily to be in sight. However, the brutal nature of the virus rears its ugly head once more as his companion Jacob succumbs to the same fate as the others.
