That’s a fun puzzle! Maybe the hero is an ordinary barista who finds a cryptic message in a latte foam and ends up on a covert mission that feels like a dreamscape—so the audience sees the spy world through everyday details. Or keep the stakes low by letting the whole operation be a high‑stakes art heist, where the “covert” part is really just the quiet backstage of a grand theater. You could play with time: the mission unfolds over one night, but we’re only told the climax first, then we flash back to see how the tight web was woven. Keep the plot tight by letting every scene serve two purposes: advancing the plot and deepening the character’s secret life. That way the audience feels the tension without feeling lost in a maze. Good luck!
