When an old enemy, Androvax the Veil, returns to Earth asking for help, the gang face a dilemma — should they trust him? Or does the legendary Vault hold an even greater terror? A second threat arises, when android guardians threaten to destroy anyone who uncovers their secrets. As the battle between Sarah Jane, Androvax and the androids reaches its climax, Rani has to save her mother from being caught in the crossfire. The Vault opens and the destiny of the entire Veil species is at stake. Is it too late to save them?
A teenage girl enters an old asylum and approaches the Vault of Secrets. She tries to access it, but only has one disc and needs two. She is confronted by the Alliance of Shades. She runs, hurts herself and falls over. Androvax, the "destroyer of worlds", exits her body and escapes. The Men in Black arrive and scan the unconscious girl. They announce the Veil is no longer in her.
Sarah Jane, Clyde and Rani are in the attic, speaking to Luke on webcam. Mr Smith interferes with a NASA space probe on Mars, as Sarah Jane wishes to prevent the probe discovering an "ancient and deadly civilisation".
Gita and her husband Haresh have joined B.U.R.P.S.S. (British UFO Research and Paranormal Studies Society, Ealing Branch) after their encounter with the Judoon and Androvax. When the couple return home on Bannerman Road, Gita spots Androvax entering Sarah Jane's front garden.
Gita gives Haresh a tyre iron and he goes to investigate. He encounters Sarah Jane, Rani and Clyde. After speaking with them, he leaves. Unseen, Androvax enters Rani's body. Sarah Jane scans for alien activity and realises Rani has been taken over by Androvax. Sarah Jane and Clyde chase him to the attic and order Mr Smith to contain him after he willingly exits Rani's body. Surprisingly, he asks for Sarah Jane's help.
They learn Androvax is dying. Since they last encountered him, he has escaped a Judoon prison in a swamp. In doing so, he was poisoned by an alien swamp viper. He is dying slowly and intends to free a hundred of his people from cryogenic sleep in the Vault of Secrets. They are the last survivors of the Veil species aside from Androvax himself. Forty years ago, their ship crashed on Earth and was sent to the Vault by the Alliance of Shades.
The three of them go to investigate a mental asylum, where they find the base of the Men in Black. They discover Ocean Waters was abducted in 1972 and met the Men in Black. The Men in Black arrive to confront them. They activate their robotic hands. They tell Sarah Jane that she must hand over Androvax and their disc or be incinerated.
The gang arrive home, where they agree to let Androvax use Clyde's body. They speak to Ocean and Minty. Ocean has the other disc needed to enter the Vault. She recalls past encounters with the Men in Black and Mister Dread. As Androvax grabs the two discs, the Men in Black arrive and tell them to prepare to be incinerated.
The incineration is averted. Androvax escapes and enters Gita's body. Gita leaves to the Vault. She is followed by Mister Dread, Sarah Jane, Rani and Clyde. Sarah Jane makes Mister Dread's car malfunction, so he acquires a new one (which he takes from a civilian by force).
They all arrive at the asylum, where Rani and Clyde rescue Gita. Androvax leaves and encounters Sarah Jane. She refuses to help him because when the Veil are reawakened and leave Earth, the spaceships will make Earth explode, ending human civilisation. Androvax feints dying to lower Sarah Jane's guard and takes over her body.
Clyde jumps away from an incineration blast from two Men in Black causing the two men destroy each other. Rani explains to her mother about aliens and how she, Sarah Jane and Clyde have met them. Mister Dread is placed into his capsule and made to sleep. Androvax goes to the Vault in Sarah Jane's body. When Rani, Clyde and Gita run in at the point Androvax wants to open the vault, Androvax pretends to be Sarah Jane. The creature lies to the gang, telling them that Androvax is dead and that they don't need to be worried about them and then opens the Vault, revealing many spaceships. Androvax leaves Sarah Jane's body, and locks himself inside the Vault, which is hyper-dimensional making it bigger on the inside. The team awaken Mister Dread, who gives up four hundred and fifty years of his energy powering the transmat device to move Androvax's spaceship into space, allowing Androvax and his race to leave without destroying Earth.
Mister Dread is low on power and declares his mission terminated. He erases Gita's memory, lest she tell the world about their experiences. He goes to sleep in his capsule.
The team returns home. Ocean and Minty arrive to ask about the Men in Black. Sarah Jane denies everything and Gita says she doesn't believe in aliens. Minty and Ocean say that the aliens have won again and leave.
Androvax is in outer space. He flies away to find a new world for his species. As the Veil ship departs, his voice can be heard narrating, "Somewhere, there is a new planet for the Veil. A new hope, it is the legacy of Androvax, a new beginning... a second genesis."
