An undercover cop chasing a drug suspect mistakenly shoots an innocent teen, and Cal is hired to determine the man's intentions. Meanwhile, Loker's lie during a recent Ponzi-scheme investigation could come back to haunt him (and Torres as well) when Cal tells them that they'll be deposed in a lawsuit over the matter; and Cal's suspicions that Foster's husband is having an affair are raised anew when he sees him again with the woman he had seen her with before.
Spoilers ahead. Coverage follows the scope labeled below.
Complete story — includes the ending
The group investigates a controversial case about a cop who shot a teenager and the threat of a terrorist attack. Meanwhile, the Lightman Group is supposedly "sued" relating to the multi-million dollar scam, but it was actually a test for Torres' loyalty to see if she would reveal what Loker did (Lightman already knew). Loker is made an unpaid intern near the end of the episode by Lightman, instead of being fired as he was expecting.
