Nash and Joe get a tip from Tony B that there is a hit out on Chief of Police Frank Girard. But it's already too late, as the Chief's car is shot up - the Chief and his driver are killed. Nash and Joe arrive to find the carnage.

The Chief was a close friend of Nash's. There was one driver, one triggerman, using a bright red Impala. The Impala crashed into a taxi, leaving behind a paint sample.

Thanks to Caitlin's suggestion, the SIU and the Embarcadero station are sharing office space in the barge. There is total chaos, as Joe is forced to share a desk with Jake Cage. Tony B is interrogated. Tony B has a new business - Bay Area Switches. The trucking business is really a front to ship money to Las Vegas to be laundered. Tony B's contact is Ellen Holiday. Holiday is in contact with the assassin of the Chief and with Jimmy Z, head of the money-laundering operation.

Holiday is arrested and questioned, but she reveals nothing. The red Impala is found, tracked to a Melvin from a wrecking ya

Nash and Joe arrive in Las Vegas, and locate assassin Roy McNeer's hotel room. His food is still warm, as Nash and Joe spot McNeer in a casino. Nash and Joe give chase, but are held up by the hotel security guards, as McNeer escapes.

Nash and Joe check into the hotel - Pepe is the concierge. They locate McNeer's girl, Vivienne Reed, and she agrees to tell Joe if McNeer calls her. The truck full of half a billion in laundered cash is hijacked. The two thugs contact Tony B to ransom the truck for $50,000. Tony B and the SIU meet them and get the truck back. Harvey, Evan, Officer Ronnie and Tony B go to Las Vegas with the truck full of money.

Jake Cage shows up in Las Vegas too, with orders from Caitlin and the Mayor's Office to bring back Nash. But Jake agrees to help Nash instead after an altercation.

Nash meets with Ellen Holiday. She fills Nash in on the rest of the DEA investigation. Jimmy Z works for a drug king pin coming in from Shanghai - they have ordered the hit on Police Chief
