Sam Hanna (LL Cool J) got a dreaded wake-up call from his son in the finale episode of "NCIS: Los Angeles" season 7.

In the sneak peek of the finale episode titled "Talion," Sam's son Aiden (Tye White) sent a message to him saying "HAZE GREY-HAZE GREY_ACADEMY OVERTAKEN BY ARMED MEN. NEED HELP."

This means that the Keating Military Academy where Aiden is studying has been invaded by a dangerous terrorist group. Sam knows that his son and the rest of the academy is in danger, which is why he needs the help of his team to rescue all the students.

According to the synopsis for the finale episode, "When Sam receives a distress code from his son Aiden that his school has been taken over by an extremist group, Sam, Callen (Chris O'Donnell), Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen) are going to rush to San Francisco to protect Aiden and free the hostages."

Will Sam and the rest of the NCIS team from Los Angeles arrive to Aiden's school to protect him and the rest of the student body on time?

Meanwhile, executive producer Scott Gemmill quashed down the speculations of the fans that Deeks (Eric Christian Olsen) will finally propose to Kensi (Daniela Ruah) at the end of season 7, after the two decided to move in together and talked about having children.

"We will not see, I don't think, a proper proposal until next season, because we have an idea for how to do that that I want to play out, the executive producer explained to TV Guide. I already know how we're going to do it. It's just, the fans have waited long enough that we want it to be worth the wait." But it does not mean that there will be more trouble in Kensi and Deeks' relationship.

The season 7 finale of "NCIS: Los Angeles" will air on Monday, May 2, on CBS.
