NCIS, 8 PM on Ch. 7 and Ch. 12:

The competitive business world of food trucks can be cutthroat, but the profession actually starts to rack up a body count in the new episode “Winter Chill,” which finds Gibbs (Mark Harmon) and his NCIS team launching an investigation after finding a man frozen to death in the back of one of these commercial vehicles. Joe Spano reprises his recurring guest role as T.C. Fornell; Lawrence Kao, Adam Ferrara and Francis Gonzalez also guest star.

On her first day back at work, Nic (Emily VanCamp) is forced to confront her trauma head on when her assailant is admitted to the ER in the new episode “First Days, Last Days.” Elsewhere, a bitter Cain (Morris Chestnut), now in recovery, is determined to destroy Mina’s (Shaunette Renée Wilson) career, while Devon and Conrad (Manish Dayal, Matt Czuchry) are bemused by the wildly erratic performance of new intern Leela (guest star Anuja Joshi) on her first day.

Craig Wright, creator of the blockbuster drama “Greenleaf,” also is behind this new series, which revolves around headstrong attorney Delilah Connolly (Maahra Hill, “black-ish”), who left a powerful position with a law firm a decade ago to raise her two children, Maia and Marcus (Kelly Jacobs, Braelyn Rankins). Now, however, Delilah’s ready to get back into court, taking cases the big firms ignore, often going up against the privileged and the powerful. Jill Marie Jones, Susan Heyward and Ozioma Akagha also are featured.
