Distancing herself from those around her, Krista spends all of her time obsessively watching a mysterious house, the house at 758.

When a fellow classmate, Jake, takes a sudden interest in her, Krista feels excited for the first time in two years, but feelings of guilt consume her, and she ends up pushing Jake away. It isn't until her grandfather makes a surprise visit from Venezuela that Krista is finally able to confront her grief and begin to let things go.
