'Law & Order: SVU' season 18 episode 10 spoilers: Team investigates assault case; EP speaks on upcoming Donald Trump-inspired episode

The team tackles an assault case on the upcoming episode of NBC's long-running procedural "Law & Order: SVU" season 18.

Titled "Motherly Love," the show's next episode will be directed by lead actress Mariska Hargitay. According to the official synopsis, the SVU will tackle a murder committed by a teenage boy. The suspect used a rifle to stop an assault on his mother, but things immediately took a different turn when he realizes that the target was someone he knows.

NBC recently released a new promo clip, and it shows Benson (Hargitay) speaking to individuals involved in the case. At some point in the teaser, a woman — who appears to be the suspect's mother — tells Benson that her line of questioning makes her uncomfortable. Benson sternly tells the woman: "Your naked selfies of you and your son's best friend are making me uncomfortable." "Law & Order: SVU" is currently on a two-week break and will return on Feb. 8. The upcoming episode also marks the procedural's milestone 400th episode.

On another note, Inauguration Day is just around the corner, but the series' take on U.S. President-elect Donald Trump is still not on NBC's primetime schedule. It was previously announced that a "Law & Order: SVU" episode centered on a Trump-like presidential candidate was supposed to be aired last year, but even the show's creator is not sure whether it would ever see the light of day.

"I don't know when it's going to air," executive producer Dick Wolf said during a Television Critics Association winter press tour panel."I never pressure the network to schedule anything in a specific way, except things like crossovers, because it's [NBC's] air. I haven't been informed when it's going to air. I suspect it will be this spring, but I don't know," he went on to say.

The 18th season of "Law & Order: SVU" airs every Wednesday night at 9 p.m. ET on NBC.
