Evolution of the Daleks

After the creation of the hybrid Human-Dalek Sec, The Doctor, Martha, Frank, Laszlo, and the other human captives manage to escape when the Doctor uses his sonic screwdriver to cause a nearby radio to emit a high-pitched frequency. Daleks Jast and Caan give chase, but confer amongst themselves concern over Sec's plan. The Doctor and Martha meet up later with Tallulah, Laszlo and Frank, and make their way back to Hooverville. The Doctor warns Solomon about the Daleks and they are seeking out more human subjects, but Solomon believes he can reason with them. As the Daleks and their Pig Slaves attack, Solomon is exterminated by Dalek Caan. The Doctor, angered by Solomon's death, tells Caan to kill him as well, but Sec orders them to bring the Doctor in. Martha tries to go as well, but the Doctor makes her stay behind, giving her his psychic paper as he, along with Laszlo, leaves with the Daleks.
At the Dalek lab at the Empire State Building, the Doctor learns that Dalek Sec's plan is to continue the Dalek race by injecting humans of high intelligence with a mix of human and Dalek DNA, allowing their minds to be programmed as Daleks. However, as the task requires more energy than the human technology of 1930 can produce, Dalek Sec plans to use gamma strike from a solar flare that will occur within minutes, and forces the Doctor to help him finalise the energy system. As Sec announces that he plans to rid the intention of Dalek supremacy from these new beings, Jast and Caan believe Sec is a traitor to their race, and stage a mutiny, changing the DNA mix being fed into the humans into that of pure Dalek. The Doctor and Laszlo manage to escape during the chaos, heading for the top floors of the building. They manage to meet Martha, Tallulah, and Frank, who had used the psychic paper to gain entry from the building's human guards. After a brief reunion, they begin to search the blueprints of the building to learn how Sec planned to collect the gamma strike energy. Martha discovers the "Dalekanium" panels on the mast of the Empire State Building, and the Doctor quickly climbs up to dismount them, warning Martha of the Daleks and their Pig Slaves following them. As the Doctor struggles to remove the panels, Martha, with the help of the others, rigs several pieces of metal from the framework of the building into the elevator, acting as a long conductor of electricity when the gamma strike hits. Though Martha is successful and electrocutes the Pig Slaves in the elevator, the Doctor fails to remove the panels in time and instead grips the mast as the strike hits. The energy transfers into the human-Dalek shells and awakens the Dalek's new army.
Martha and the others recover the Doctor, and they flee to Tallulah's theater, with the human Dalek army following them in the sewers. As they are surrounded by the human Dalek army, they find that Dalek Thay and Jast have Sec in chains. As the two prepare to exterminate the Doctor, Sec tries to reason with them and then steps in the way of their blaster fire, sacrificing himself to save the Doctor. The Daleks order their army to kill the Doctor, but find that the humans are resisting; the Doctor, by exposing himself to the gamma strike, caused some of his Time Lord DNA to transfer to the human shells and give them freedom from Dalek control. The human Dalek army turn on Thay and Jast, killing them, but Dalek Caan, watching from the Empire State Building, activates a termination sequence and kills the rest of the army. The Doctor returns to the Dalek lab to face Caan, offering mercy and aid, but instead the Dalek escapes via his emergency temporal shift. As the Doctor regroups with the others, Laszlo begins to die, due to his partial transformation as a Pig Slave. The Doctor however, finds a cure to stabilise his condition, although it will not restore his human appearance. Laszlo and Tallulah are reunited, and learn from Frank that the people of Hooverville will take Laszlo in despite his looks. The Doctor and Martha finally return to Liberty Island and the Tardis, where the Doctor muses that there is to be yet another confrontation with the Daleks in their future.
