Whakarāpopototia te tuhinga:  Kei te whawhai tonu ia ki te tiaki i a tātou i te whakatumatuma me te tini o ētahi atu whakawehi nui o te ao o nāianei. Na ka whakaaro pea koe he nui ake ngā mea hei āwangawanga mā te MI5 i te whakahaere i tētahi whakataetae mō ngā kaimātakitaki o Blue Peter kia haere ki te "wānanga mātakitaki". Engari koinei tonu te mea i tupu, i muri i te wikitoria o nga taiohi tokotoru i te whakataetae ki te toro ki te MI5's London HQ. I tae atu anō ngā tamariki ki te hui ki te kaiwhakahaere matua o te ratonga haumaru, a Andrew Parker. Ko ngā kaiwhakataetae toa me Andrew Parker o MI5 (māui). I whakaaetia te rōpū ki roto i te tari matua o te ratonga. Ko te Bonds taitamariki (e kitea ana i konei e Daniel Craig) i whiriwhiria i roto i ētahi atu tūmanako 5,700. Ko Jamie, 13, Reuben, 13, me Finley tekau tau te pakeke i tohua i muri i te raupapa o ngā whakamātautau "tino uaua" hei whakaatu he kaitirotiro rangatahi rātau. Ko te ingoa waehere Project Petra, ko te kaupapa tuatahi i whakaaetia ai nga kāmera ki te kiriata i roto i te whare MI5. Ka tae mai tēnei i te wā e nui ake ana te kaha o ngā tari matauranga o te UK i ngā wā o mua ki te whawhai ki ngā whakawehi mai i Al Qaeda, Islamic State me Rūhia. Ko to rātau āheinga ki te whai i ngā kaiwhakatuma o tāwāhi, o te kāinga hoki, me te aroturuki i ā rātau whakawhitiwhitinga, kua tino whara i ngā rerenga mōhiohio nā te kaitātaki o mua o Amerika, a Edward Snowden. Tata ki te 5,700 ngā tamariki i tono ki te whakataetae, ā, koia tētahi o ngā whakataetae rongonui rawa atu i roto i te hītori o Blue Peter. Me whakaoti ngā kaitono taitamariki i tētahi raupapa wero, me te whakamīharo i tētahi rōpū kaiwhakawa i hangaia e te kaituhi tamariki a Anthony Horowitz, te kaiwhakarato pouaka whakaata me te kairipoata a Sonali Shah me te Ahorangi Christopher Andrew, te kaituhituhi a te Ratonga Haumarutanga. Me whakaoti e ngā kaitākaro whakamutunga tētahi raupapa tohu hei whakatau i te wāhi o te'kura tutei' i Manchester. Ko te tokotoru waimarie me te kaiwhakahaere matua a Andrew Parker (maui) me te kaiwhakaatu o Blue Peter a Barney Harwood (tuarua maui) I roto i te waahanga o te wiki kua hipa, e waru nga kaitono whakamutunga i patu i nga waehere hei whakatau i te waahi o te "kura tutei", i whakatuhia ki nga tari o te umanga kaute a KPMG i Manchester. A inanahi, ko nga kaitono...
Ko Jamie, 13, ko Reuben, 13, ko Finley, 10, kei te haere tonu ki te noho hei wairua. I whakaaetia ngā kāmera pouaka whakaata ki te tari matua o Rānana mō te whakaaturanga tamariki anake. I tutaki atu a Trio ki te tumuaki o te ratonga haumarutanga a Andrew Parker. Ka tae mai a Stunt me te MI5 e kaha ake ana ki te whawhai ki te whakamataku me te piki ake o Ruhia.
