Here is a possible summary:
A security officer and his superior watch the Gate Guardian, a colossal angel that guards the entrance to Eden, where the Tree of Life is. Doctor Montauk, who is obsessed with the Scarlet King, an interdimensional warmonger, arrives and tries to communicate with the Guardian. He receives a psychic vision of a past battle between the Guardian and the King, who wanted to destroy the Tree of Life. The King realized he was not strong enough and made a deal with the Guardian to let him in when the Rapture happens. Montauk snaps out of the vision and asks the Guardian if it agreed to the deal, but only gets a command to leave. The summary ends with links to other videos about the Scarlet King.
