Martha Jones calls the Doctor back to present-day Earth, where UNIT is investigating ATMOS ΓÇö a sat-nav device fitted in millions of cars worldwide that has been cutting emissions to impossible levels. The Sontarans are behind it, working through a brilliant but naive teenage prodigy named Luke Rattigan who believes they are his allies. Donna returns home to find her family unsettled by her absence. The episode builds steadily toward catastrophe as the Sontarans prepare to use ATMOS devices to poison Earth’s atmosphere and convert the planet into a clone-world breeding ground.
ΓÇ£The Sontaran StratagemΓÇ¥ follows the Tenth Doctor as he reunites with Martha Jones and UNIT to investigate ATMOS, a new car system that is causing global environmental changes. It is revealed to be part of a Sontaran invasion plan.
ATMOS is a car-based system designed to reduce emissions, but it secretly releases a toxic gas that prepares Earth for invasion. It is controlled remotely by the Sontarans as part of their military strategy.
The Sontarans are a clone warrior race obsessed with warfare and honour in battle. They view Earth as a strategic opportunity for conquest and experimentation.
UNIT, the Unified Intelligence Taskforce, works with the Doctor to investigate and respond to the alien threat. Martha Jones is now a UNIT medical officer, assisting in the global crisis response.
This episode continues the Earth-based alien invasion tradition in Doctor Who, and further develops the role of the Tenth Doctor working alongside former companion Martha Jones in a professional capacity.
