History
The South Glade Mission Church was infamous for its racist views against many people (mostly Jews and black people). Kingsman agent Harry Hart soon learned that the church has a connection with notorious global entrepreneur Richmond Valentine (due to many of the attendants using his SIM cards that grant free lifetime cellular and Internet connectivity). Visiting the church during a sermon, Harry is disgusted by the group's racism and decides to leave, but this gets noticed by a woman, who started spilling out racist remarks on him.
However, noticing the incident through a video transceiver, Valentine activates the SIM cards in the church, triggering a signal that causes all of the attendants (including Harry) to become murderously violent and attack each other to the deaths. Hart manages to survive the event by using his spy training to kill anyone who tries to attack him (including the church leader), but is left distraught after seeing that everyone in the church is dead.
Harry soon learns that Valentine is responsible for the incident just the latter confesses about his true plan to use the SIM cards to exterminate much of humanity for a new world order, and that the event on the South Glade Mission Church was nothing more than a test to see what would happen.
