The Sontaran Stratagem The Doctor's Daughter

The Poison Sky is the fifth episode of Series 4 and the second of a two-parter starting with The Sontaran Stratagem.

Plot

Unhinged manlet Luke Rattigan has joined forces with General Staal and the other manlets in the hope of creating a new human race in some Utopia-like place. Unfortunately it turns out the Sontarans are just ruseing him but in the end he manages to BTFO of them (squeezing in a cool one-liner to boot).

Basically the same as the last episode, the Sontarans are trying to poison Earth and Teninch, Donna, Martha and UNIT have to stop them. There's also a clone of Martha on the loose, at least until she dies.

Reception

Enjoyed it. Good performances by the manlet playing Luke Rattigan and by General Staal. The Ten/Donna/Martha dynamic is pretty good too. No one remembers this episode. May as well be not canon.
