Wisdom of the Crowd is a drama about a visionary tech innovator who creates a cutting-edge crowdsourcing app to solve his daughter's murder, and revolutionize crime solving in the process. Inspired by the notion that a million minds are better than one, Silicon Valley entrepreneur Jeffrey Tanner, develops "Sophe", an online platform for publicly shared information he's certain will find his daughter's killer. To assist him, Tanner recruits Detective Tommy Cavanaugh, the original cop who investigated the murder but was unceremoniously forced off the case. Working with them is Sara Morton, a brilliant engineer whose relationship with Tanner goes beyond professional; Josh Novak, a talented, nerdy-cool head programmer; and Tariq Bakari, a tech genius and expert hacker with issues adhering to the rules. Concerned with Tanner's obsession is his successful ex-wife, Congresswoman Alex Hale, with whom he shares an unbreakable bond over their shared grief. As Tanner taps into the "wisdom of the crowd", his unexpected success fuels his determination to solve even more cases than just the one that's personal to him.
A user of Sophe, the cutting-edge crowdsourcing platform, uploads new footage of Jeffrey Tanner's daughter, Mia, being strong-armed by an unknown man five months prior to her murder. Also, Tanner enlists Sophe to help with Cavanaugh's case of a missing teenager.
Tanner's previous company claims Sophe was created using their copyrighted codes and legally threatens to shut down the organization. Also, Cavanaugh works with Tanner to solve the murder of a retired detective after his boss removes him from the case due to a personal connection with the family.
After Sophe users uncover recent security footage of a domestic terrorist missing for 20 years, they daringly track his every move, even as federal agents threaten to shut the platform down. Also, Tanner's former company files an injunction against Sara forbidding her to work with Sophe or communicate with the staff.
The team utilizes Sophe to track a killer who is targeting online celebrities and broadcasting their final moments on a live streaming platform. Also, within 24 hours, Sara will know if she is legally allowed to work with Tanner and Sophe or forever banned from the platform.
Tariq has a personal case for Sophe after his childhood friend is the target of a violent stalker. Also, Tanner desperately tries to locate a recently deported individual that a Sophe user identified as a key witness in Mia's murder case.
