A female is seen playing SkeeFree, a classic 1991 computer game that involves skiing an endless slope while escaping a violent monster.

While playing the game, the female contemplates the metaphorical connection between the inevitable in-game death at the monsters claws with death in real life.

But, no sooner than her thought is complete, a male character informs her of a secret that will allow her to escape the clutches of the monster and, thereby, in-game death. This leaves her in a confused state as she contimplates the possible avoidal of all forms of death.
