In a Victorian Gothic mansion, strange things are afoot. The master of the house, away in Egypt, has been replaced by a sinister Egyptian. Cloth-wrapped Mummies roam the grounds, killing people. Beneath a pyramid, the last of the Osirans — Sutekh the Destroyer — waits to be freed, to at long last bring his gift of death to all who live.

It was Jon Pertwee's final season as the Doctor and included, very briefly, the first appearance of Tom Baker as the Fourth Doctor. The Time Warrior, the season opener, introduced Sarah Jane Smith, who was a frequently featured character in the Doctor Who universe decades after her departure in Season 14. The same story also, for the first time, named the Doctor's homeworld as Gallifrey. UNIT also began to be phased out of the series during this season.

It was during this season that the Doctor cut ties to UNIT (after Terror of the Zygons, the Brigadier would not appear again until Mawdryn Undead in 1983, and The Seeds of Doom marked the last occasion to date that the Doctor was explicitly said to be working for UNIT - as opposed to working with them as occasions warranted). Several of the serials in this season, particularly Pyramids of Mars and The Brain of Morbius, are among the best-known of the 1970s-era storylines. Though it was aired as a part of Season 13, Terror of the Zygons was actually filmed as part of the previous season; this holdover allowed the series to switch back to an autumn season start.

The Doctor and Sarah reach Earth and try to warn the research centre about the Kraal invasion before Styggron unleashes his virus.

Philip Hinchcliffe era
The planet Karn is home both to a mystic Sisterhood, whose sacred flame produces an elixir of life, and to Mehendri Solon, a fanatical scientist who is using the remnants of spaceship crash victims to put together a new body for the still-living brain of the executed Time Lord criminal Morbius.
When the Doctor and Sarah arrive on the planet, Solon decides that the Doctor's head is just what he needs to complete his work. The Sisterhood meanwhile fear that the Doctor has been sent by the Time Lords to steal the last drops of elixir produced by the dying flame. They kidnap him and plan to burn him at the stake but he is rescued by Sarah, who is temporarily blinded in the process.
The Doctor is tricked by Solon into believing that his companion's condition is permanent. He asks the Sisterhood for help and restores their sacred flame to its former glory using a firework to clear its blocked chimney. Returning to Solon's citadel, the Doctor and Sarah become trapped in the cellar.
The Doctor releases cyanide fumes into the ventilation system and Solon is killed, but not before he has used an artificial brain case to complete Morbius's new body. The now-mobile Morbius accepts the Doctor's challenge to a mind-bending contest, which takes a heavy toll on both of them. The Sisters force the crazed Morbius over a cliff and he falls to his death. They then use the elixir to heal the Doctor.

The season is notable for the departure of Sarah Jane Smith in The Hand of Fear and for The Deadly Assassin, a story set entirely on Gallifrey which expounded greatly upon the culture and history of the Time Lords, and the Eye of Harmony and Rassilon are mentioned for the first time. The Deadly Assassin also featured the return of the Decayed Master in a degenerated form and had the Doctor without a companion for an entire story for the first time in the history of Doctor Who. This story is also the first time the limit of regenerations is set.

The Doctor and Sarah arrive in a quarry during blasting operations and when Sarah is buried under rubble, she discovers a stone hand.

Can the Doctor, now in his fourth incarnation, recover from his post-regenerative trauma to save the m.youlady.cc Earth from Think Tank and their plot for world domination?

The Doctor, Sarah and Harry arrive on a desolate and apparently deserted Earth to discover that a group of shipwrecked astronauts from a human colony, GalSec, have been lured there by a fake distress call. One of their number, Roth, tells Sarah of an alien conducting gruesome experiments on him and his crewmates. The alien turns out to be a Sontaran, Field-Major Styre, who is compiling a report on human physical and mental capabilities as a prelude to an invasion of Earth.
The Doctor challenges Styre to unarmed combat. The Sontaran agrees but is quickly weakened in Earth's unfamiliar gravity. Harry meanwhile enters Styre's ship and uses the Doctor's sonic screwdriver to remove the vital terullian diode bypass transformer, so that when the alien returns there to revitalise himself he is drained of all his energy and destroyed.
The Doctor sends a message to the Sontaran fleet, warning them that without Styre's report they cannot invade.

The TARDIS arrives on an apparently deserted and deactivated space station Nerva, otherwise known as the Ark, orbiting Earth in the far future. There the Doctor, Sarah and Harry discover the last survivors of the human race held in suspended animation, Earth having been evacuated thousands of years earlier when solar flares threatened to destroy all life.
The station has been visited by a Wirrn, an insect life form, which has laid its eggs in the solar stacks and absorbed the body and mind of one of the sleeping humans. The Doctor's reactivation of the station's systems causes the humans to start to revive. Their leader, nicknamed Noah, becomes infected by one of the emerging larvae and is slowly taken over.
The Doctor and his friends meanwhile gain the trust of the other humans, now led by a med-tech named Vira. Together they manage to lure the hatched Wirrn insects into a shuttle craft and then eject it into space.
In a final act of humanity, Noah - by this time fully transformed into a Wirrn - deliberately neglects to set the shuttle's stabilisers, causing it to explode.
