Kinda is the third serial of the 19th season in the British science fiction television series Doctor Who, which was first broadcast in four twice-weekly parts from 1 February to 9 February 1982.

An Earth colonisation survey expedition to the beautiful jungle planet Deva Loka is being depleted as members of the survey disappear one by one. Four have gone, leaving the remainder somewhat apprehensive. Sanders relies on bombast and rules, while Hindle his deputy, is close to breaking point. Only Todd the scientific officer, seems to deal with the situation with equanimity. She does not see the native people, the Kinda, as a threat but rather respects their culture and is intrigued by their power of telepathy. The social structure is also curious in that women seem dominant and are the only ones with the power of voice. The humans are holding two silent males hostage for "observation". Todd believes they are more advanced than they first appear, as they possess necklaces representative of the double helix of DNA, indicating a more advanced civilisation.

Elsewhere in the jungle, the TARDIS crew are also under stress, especially Nyssa, who has collapsed from exhaustion. The Fifth Doctor constructs a delta wave augmenter to enable her to rest in the TARDIS, while he and Adric venture deeper into the jungle. They soon find an automated total survival suit (TSS) system, which activates and marches them to the Dome, the colonist base. Sanders is a welcoming but gruff presence, further undermining Hindle at regular intervals. Sanders decides to venture into the jungle in the TSS, leaving the highly-strung Hindle in charge. His will is enforced by means of the two Kinda hostages, who have forged a telepathic link with him, believing their souls to have been captured in his mirror. The Doctor, Todd and Adric are arrested as Hindle now evinces megalomania.

Tegan faces a more metaphysical crisis. She has fallen asleep near the euphonious and soporific Windchimes, unaware of the danger of the dreaming of an unshared mind (one not engaged in telepathy with another humanoid). Her mind opens in a void, where she undergoes provocation and terror from a series of nightmarish characters, one of which taunts her: "You will agree to being me, sooner or later, this side of madness or the other". The spectres are a manifestation of the Mara, an evil being of the subconscious that longs for corporeal reality. Mentally tortured, she eventually agrees to become the Mara and a snake symbol passes to her arm. When her mind returns to her body, she is possessed by the Mara. She passes the snake symbol to the first Kinda she finds, a young man named Aris, who is the brother of one of the Kinda in the Dome. He too is transformed by evil and now finds the power of voice.
