Jeffrey Tanner is obsessed with finding who murdered his daughter and has developed an online, crowd sourcing app called Sophe to help him. His team is a unique collection of talented individuals with many different skills.

A 13 year old boy turns up missing, so Tanner uses Sophie to help find him.

Crime data is entered into Sophe looking for links to Mia. Instead it links 3 previously unrelated cases. When Cavanagh adds a clue it jumps to 14 and keeps climbing with crowd help. Meanwhile Carlos Ochoa is threatened in prison.

Tanner has to deal with cyber attacks when they are asked to help solve the murder of a white supremacist. Tanner and his wife are at odds when private information is leaked to Sophie regarding their deceased daughter.

A medically retired Inspector is murdered. Cavanaugh is not allowed on the case due to his prior involvement with the widow, so he seeks Tanner's help. Meanwhile, Tanner's prior company alleges he stole their code to create Sophe.

A computer expert creates a game that targets short-attention span teenagers and compels them to commit suicide. Meanwhile, a clue emerges in a photo of Tanner's daughter.

Tanner is offered new evidence in Mia's case if Sophe can prove someone is innocent of murder. Tanner and Sara begin depositions with AllSourcer for the rights to Sara's work and Sophe's code.

The team tracks a killer targeting online celebrities and broadcasting their final moments on a live-streaming platform; Sara worries about being banned from using Sophie

Jeffrey and detective Tom speak to Carlos, and he remembers something vaguely about a man taking a selfie with Mia on her phone. But something is wrong.

Tanner and Hale go to court to convince a judge to free Carlos. A man who was obsessed with Sophe, including Mia's case, is found dead. Investigating this man leads Tanner to information revealing a city official's killer.
