Overall Content Rating: Parents Strongly Cautioned PG-13
This FBI thriller follows agents tracking bomb plots, corporate intrigue, and violent attacks. Expect recurring moderate profanity in workplace and field dialogue, a few isolated strong swear words, and moderate violent imagery tied to shootings and explosions rather than prolonged graphic torture. There is no sexual content on the page in the sampled material; reviewers note the series avoids gratuitous sex. Parents may note a single conversational reference suggesting a minor character was gay, plus mild name-calling and slang alongside the action-heavy tone.
