the Doctor attempts to mediate an interplanetary war between three stellar empires, a war which Roz and Chris become caught up in, Benny meets and falls in love with a displaced human drifter and con-artist named Jason Kane. The two decide to get married. The Doctor arranges a gala wedding in the English village of Cheldon Boniface, in the early 21st century, home of Ishtar Hutchings, the former Timewyrm. He invites and provides transportation for guests from points throughout time and space, including Ace, Kadiatu, Irving Braxiatel and Sherlock Holmes and Watson. The wedding is interrupted by the Master, who had stolen a Gallifreyan relic to build himself a new body, and had created a Fortean flicker to distract the Time Lords with improbable coincidences; however, his plan had backfired when the flicker caused the Doctor to coincidentally arrive to arrange Benny's wedding. The Master's backup plans are defeated with the help of Ishtar; the temporal energy she releases also rejuvenates the aging Brigadier Lethbridge-Stewart. The Fortean flicker also returns the Doctor's original TARDIS from the alternate reality where it had been seemingly destroyed. The Doctor gives Benny and Jason two time rings as wedding presents. On Mars shortly before the Dalek invasion of Earth, the Doctor, Roz and Chris discover a plan by a rogue Ice Warrior faction to assemble an ancient Osirian weapon to wreak revenge on the human colonists who have driven them off their planet.

Benny then contacts the Doctor, asking for his help in discovering what happened to her father Isaac Summerfield, a Spacefleet Admiral who disappeared during a crucial battle with the Daleks. The Doctor and Bernice discover that Isaac's ship was caught in a time rift and ended up on Earth in the twentieth century. They find Isaac in an English village in 1983, running an underground railroad for stranded aliens. While Chris and Roz become closer, the Doctor and Benny deal with a plot to change human history. The Doctor recovers the trail of the mysterious Brotherhood in 1880s Paris, where several secret societies are using psychic powers to their own advantage.
