Lim (Malana Lee) was a member of the Koreans United for Freedom (KUF), a rogue paramilitary organization led by Kang Yeonsak in Olympus Has Fallen. Lim posed as part of the visiting delegation of the South Korean Prime Minister. Once having successfully infiltrated the Presidential Emergency Operations Center, her group revealed their true intentions by killing the remaining Secret Service agents in the bunker and holding President Benjamin Asher, Vice President Charlie Rodriquez, Secretary of Defense Ruth MacMillan, and the Joint Chiefs of Staff. Lim was primarily the technician of the group, working the computers in the bunker and manning the CCTV system around the White House. She also input the codes to activate Cerberus, the system responsible for the self-destruction of America's nuclear arsenal.
Lim later killed herself in a helicopter explosion along with some unidentified terrorists and hostages meant to pass on as Kang and President Asher.
