The Vault is a post-apocalyptic sci-fi web series that follows a ragtag group of survivors living in an underground military bunker known as Vault 175 or the Vault. The group is led by Evelyn Pierce, a no-nonsense General in the Canadian Armed Forces.

Buried five miles beneath the Earth, this state-of-the-art facility is humanity's only remaining home.
Outside there is only nuclear winter, a wasteland in which it is believed nothing and no one can survive...until one day when a surveying mission discovers an unconscious pilot by the name of Nathaniel Hale.
