Mac and crew receive a cryptic note from undercover officer Trigamundo during an
investigation into the state's largest drug ring. At a stakeout of the Embarcadero Hotel where
a large drug buy is supposed to take place Shields shoots Mac Shields is taken into custody.
But their real target the top man a.k.a. The Possum is tipped off not to appear for the buy
so he eludes capture. At the hospital a wounded Mac is lying on a guerney in a corridor
heavily sedated and awaiting surgery when Mac hears cries coming from a nearby room. Mac
staggers towards the cries and sees two masked orderlies smothering a man with a pillow. Mac
tries to stop them but he is groggy and has lost a lot of blood. When Mac awakens from surgery
there are no dead bodies which support his hazy memories. Hospital personnel try to convince
him and Sally that he dreamt or hallucinated the entire incident. But did he? Mac stubbornly
leaves the hospital and he and Enright continue investigating. A fresh look at Trigamundo's
note puts a whole new light on the case... but only if Mac can stay alive long enough to solve
it
