Unsolved: The Murders of Tupac and The Notorious B.I.G.

In 1997, Detective Russell Poole launches the first major investigation into the murder of the Notorious B.I.G. Ten years later, Detective Greg Kading is asked to re-open the still-unsolved case.

Kading and Dupree brief the Biggie Smalls Task Force on the case's popular theories. Poole and Miller travel to Las Vegas to investigate a possible connection between Biggie and Tupac's murders.

Frustrated by their lack of progress, the Task Force questions Kading’s leadership. RHD investigates a bank robbery. Biggie warns Tupac that his new friends are dangerous.

The Task Force tracks down a person of interest; after Poole gets put on a new case, Miller interviews Biggie's widow; Tupac faces legal trouble and goes to record at Quad Studios in New York.

Poole and Tyndall investigate a dirty cop; the Task Force receives promising results from a ballistics test; Biggie releases "Who Shot Ya," spurring Tupac to make a risky alliance.

Poole takes his theory about Biggie's murder outside of the LAPD; Kading and Dupree have a long-awaited sit down; rising tensions between Biggie and Tupac boil over at the Soul Train Awards.

The Task Force gets help from an FBI informant with a questionable past; Poole shares his work with Voletta Wallace; after being shot, Tupac clings to life in a Las Vegas hospital.

The Task Force has a new target; Poole runs into his old partner, who has updates on the Biggie case; Voletta Wallace visits her son's hotel room the day after his death.

Kading and Dupree meet with an increasingly agitated Poole. Running out of options, the Task Force gambles with a dangerous bluff.
