During Gwen's (Eve Myles) morning off with her boyfriend Rhys (Kai Owen), they both see news reports of UFO sightings over the Taj Mahal, and an armed clash between CO19 officers and English civil war era soldiers. When she returns to the Hub, the team learns that they are caused by unstable rift activity after it was opened to rescue Tosh and Jack. Torchwood has its hands full; Tosh and Owen (Burn Gorman) investigate cases of the Black Death in a local hospital, where Tosh sees a glimpse of her mother, while PC Andy informs Jack and Gwen that they have a Roman soldier in police custody. In that time, Gwen sees a glimpse of Bilis Manger (Murray Melvin). Ianto (Gareth David-Lloyd) sees Lisa (Caroline Chikezie), who tries to convince him to open the rift. During a heated argument, Jack fires Owen. While at a bar, Owen sees Diane (Louise Delamere), who tries to convince him to open the rift.
