Peter is then seen prepping for a school trip to Europe. He considers leaving his Spider-Man suit at home, heads abroad and takes part in awkward yet playful flirty banter with Michelle Jones (Zendaya).

But while talking in his hotel room with bestie Ned (Jacob Batalon), Ned suddenly hits the floor from a tranquilizer dart shot at him by Fury, who's sitting right in the shadows of the room. Suddenly, Peter finds himself recruited on some kind of mission that shows him webslinging through London, briefly donning a black suit and aligning with Gyllenhaal's Mysterio (traditionally a Spider-Man villain) and fighting what appears to be Hydro-Man.
