Midseason premieres are coming, and NBC is teasing a new show.

The official trailer for the upcoming series "The Enemy Within" has dropped, and it is intense and emotional. It introduces Erica Shepherd (Jennifer Carpenter), a former CIA operative who gave up the names of four others in order to save her daughter. Now serving time for treason, she gets a chance to redeem herself when her help is needed to track down a dangerous criminal.

The trailer highlights the complicated dynamic between Erica and FBI Agent Will Keaton (Morris Chestnut). Her betrayal led to his fiancée's death, so he has his doubts about her. Although he doesn't appear to know quite what to make of her, she seems determined to get back at the person who ruined her life.

Watch the trailer below.



"The Enemy Within" premieres Monday, Feb. 25 at 10 p.m. ET/PT on NBC.
