It features a rebellious faction of shapeshifting aliens, the Skrulls, plotting an insurgency on Earth after Nick Fury had failed to find another planet for them.

Returning to Earth to meet with Talos, Fury learns the latter has been exiled from the Skrull Council and former ally Gravik has taken a leadership position with the rebels.

After he claims Gravik killed her mother Soren, G'iah reveals the rebels plan to attack Vossoyedineniye Square on Unity Day and marks the bombs' locations.

[23] According to Whip Media's TV Time, Secret Invasion was the most watched original series across all platforms in the United States during the week of June 25, 2023.

The site's critical consensus reads, "It's good to see Samuel L. Jackson's Nick Fury again after an extended exodus, but this premiere's plodding setup gets Secret Invasion off to a curiously inert start.

Furthermore, he thought the episode had introduced too much information and had not dealt with the psychological aspect of its protagonist to the extent of other shows such as WandaVision (2021) and Hawkeye (2021), feeling that it instead "reheats a snippet of the stinger shown after the credits of Captain Marvel before carrying on".

She did not like the Skrull storyline, calling it "dead in the water", and opined that Fury's personal struggles were more interesting than the relationship between Talos and G'iah, and wanted the series to focus the most on that one.

[8] Matt Purslow, writing for IGN, gave the first two episodes an 8/10, primarily remarking that he felt the premise lacked "authentic tension" as many characters were already revealed to be Skrulls while also expressing concern of the show's concept provided that it's not heavily reliant on the 2008 comic book storyline of the same name by Brian Michael Bendis.
