Everybody needs time to have fun outside of work. Det. Danny Messer (Carmine Giovinazzo) and Det. Don Flack (Eddie Cahill) decide to take a break from dead bodies and attend a basketball game. It's not long before crime says hello.
After Dugan Scott collapses center court, no one in the stands looks away. Flack senses something is amiss, and he and Danny head down for a closer look. Dr. Sid Hammerback (Robert Joy) later tells Danny and Det. Lindsay Monroe (Anna Belknap) death was due to belladonna poisoning.
A color-changing lipstick turns out to be the game changer. One of the cheerleaders, Paula Tolomeo, wanted revenge for a past humiliation.
Meanwhile, Det. Mac Taylor (Gary Sinise) and Det. Stella Bonasera (Melina Kanakaredes) have a stickier situation. A corpse lies in a fountain, and it looks like the killer cabbie's work! This makes the fifth victim to die. Eventually, another is uncovered. This is not good.
Mac holds a press conference since media speculation has citizens worried. Reed Garrett (Kyle Gallner, Big Love) is there, and he asks if Mac would take a cab. The answer is no, the killer must be caught first. This ticks off Jordan Gates (Jessalyn Gilsig, Nip/Tuck), the mayor's criminal justice coordinator. She points out this is one person, and cabs are critical. Mac says people can get around if need be.
Back at the lab, he tells Stella and Dr. Sheldon Hawkes (Hill Harper) everyone is going to work as much as it takes to get this perpetrator whether that means working double shifts, overtime, etc.
The cabbie as killer is an interesting angle, but the storyline has continued beyond what's reasonable. Next week is the second to last season episode. Catch this person already! I'm tempted to think Jordan is behind it all. Yes, it's farpfetched, but…
Reed has come into his own! He has a job to do, but so does Mac. Okay, Reed may have not mentioned Mac by name. However, he must have phrased things so readers would understand. Mac's warning about not taking a risk was a wise one, since killers read, too.
Rikki Sandoval (Jacqueline Pinol, Lincoln Heights) is moving away, out of Danny's life. This is a good thing, but Lindsay is perhaps not best for him.
