When you watch NCIS Season 15 Episode 10 online, Torres and Sloane are working a protection detail for a senator who is touring a military base in Afghanistan when Gibbs calls to inform them that the senator's son has been critically injured and isn't expected to survive. The clock is ticking and time is of the essence. Unfortunately, there won't be any aircraft available at that base for a couple days, which would be too late to reunite the senator with his son, so he decides that they will travel to another base overland and catch a plane from there. Meanwhile, back in the United States, Agent Bishop peeks at Metro PD's files and figures that there is something suspicious about the circumstances in which the senator's son was injured. She doesn't believe that he fell down the stairs in a drunken stupor and suspects that foul play was invovled. Her suspicions prove justified when Abby's computer model demonstrates that he fell down the stairs backwards and with significant force -- Chandler Phillips was pushed down the stairs by someone else. It's up to the NCIS team to both see Senator Phillips home safely but to discover the truth behind his son's devastating injuries.
