Double `Doctor Who' action starring Colin Baker and Patrick Troughton. The sixth and second Doctors cross paths while tackling the deadly Sontarans.

Both Doctors unite to prevent evil foes from experimenting with time; something lurks in the space station; evidence suggests Time Lords are responsible, but the Doctor refuses to believe it.

With the goal of time travel, the Androgum and Sontarans prepare to double-cross one another. The two doctors are left with a difficult decision to make.
