While traveling through time with his companions Amy Pond and Rory Williams, the Doctor is surprised when the TARDIS gets rocked by an unknown force. It’s not until the Doctor actually opens the door of the ship to see the source of the collision: Booster Gold, Skeets and an unconscious Rip Hunter in the Time-Sphere. Booster and Skeets explain that, while on the trail of time traveling villain Per Degaton, their shipped was rocked by an unseen force that was still after them. As they finish their tale and the Doctor takes a look at Rip, the unseen force reveals itself to our heroes: the combined might of the Daleks and Per Degaton. Knowing space is no place to do battle with these enemies, the Doctor throws a time lasso around the Time-Sphere and transports the whole party to an abandoned Earth outpost. The battle rages on, with Rip eventually coming to in time to assist the Doctor with his plan to defeat the villains.
