After escaping the Cybermen, the party heads to Battersea Power Station, where Lumic controls the people of London who wear EarPods with a transmitter and sends them to be transformed into Cybermen. Ricky is killed by the Cybermen en route. To halt the conversion, the group divides into three smaller groups. Following Mrs. Moore’s murder, the Cybermen kidnap the Doctor, Rose, and Pete and bring them before Lumic, who has assumed the role of Cyber Controller. The humans who had not been converted are set free when Mickey and Jake turn off the zeppelin’s transmitter. In order to send the code to Rose’s phone to cancel each Cyberman’s emotional inhibitor, Mickey breaches Lumic’s database. The Doctor then plugs the phone into the computer systems, altering the signal and sending the Cybermen into despair. Lumic is killed when Pete cuts the ladder he is ascending as they flee the exploding factory on the zeppelin. Given that he knows Rose prefers the Doctor, Mickey chooses to stay and assist Jake in repairing the parallel universe while also caring for Ricky’s grandma.
