Toshiko falls for a handsome soldier trapped out of his time, who unwittingly holds the key to saving the world, in this week's instalment of the award-winning drama created by Doctor Who writer Russell T Davies.
With an old hospital haunted by ghosts from 1918, a crisis foreseen by Torchwood 90 years ago is about to reach its climax. Time zones are colliding, but, with life-and-death decisions to be made, will Torchwood be able to stop an explosive end for the city of Cardiff?
Toshiko is played by Naoko Mori.
