'Law & Order: SVU' Season 18 air date, spoilers: Team to collaborate with US Vice President on next mission?

In the upcoming season of NBC's police-procedural drama series "Law & Order: Special Victims Unit," Lieutenant Olivia Benson (Mariska Hargitay) and her team will collaborate with US Vice President Joe Biden to solve their current case.

Biden will have a cameo role in the series and will be voicing his concern on sexual violence against women. He will also emphasise on the issues of untested rape kits and will be seen promoting the efforts to end women abuse.

Both Biden and Hargitay are known for advocating women's rights and putting an end to violence against them. Hargitay recently attended the United States of Women Summit held at the White House to discuss the importance of testing the rape kits in order to capture the culprits and punish them.

According to Yibada, in a press release made available by the network, it is mentioned that the Vice President will be appearing in a media conference scene where he will be praising the efforts of Lt. Benson and her team for working on the national rape kit back-log in the city of Detroit.

Other guest stars who will be appearing in the upcoming season are Henry Thomas of "E.T.: The Extra Terrestrial" fame and Kelli Williams of "The Practice."

Thomas will be playing the role of a convict who will be cleared of all the charges after spending 16 years in prison. Soon after his release, he will be again accused by a woman (portrayed by Kelli Williams) of raping her. Detective Fin Tutuola (played by Ice T), who had investigated the earlier case of the alleged serial rapist, will be called in to investigate the case.

The Hollywood Reporter has stated that the upcoming case will be based on Netflix's criminal-drama show "Making a Murderer" in which Steven Avery was arrested for a second time after he completed his first sentence that was 18 years long.

"Law & Order: SVU" Season 18 will premiere on Sept. 21 on NBC.
