The series centers on established Cortez siblings Carmen and Juni (voiced by Ashley Bornancin and Carter Hastings) leading junior agents through Spy Academy training and missions against villains like Golden Brain. Episode plots rely on classic elements such as rivalries, exams, gadget use, and thwarting schemes, including musical mischief in "Songs in the Key of Pain" and destroying the enemy's lair in "The Cookie Crumbles," with no dialogue, arcs, or subplots addressing systemic issues, identity politics, or critiques of traditional norms. The Cortez siblings remain unchanged from the source material, and any supporting team diversity stays incidental to the kid-spy premise rather than thematically central.

A minor 2018 voice-casting controversy involved white actor Travis Turner voicing the black character PSI, yet this remained isolated to one supporting role and bore no connection to narrative themes or creator intent. The result is straightforward entertainment that prioritizes adventure over messaging.
