At the Television Critics Association winter press tour on Tuesday, the first trailer was unveiled for CBS’s The Red Line.

Written by Caitlin Parrish and Erica Weiss, here’s the official description for the series:

THE RED LINE is an eight-episode event series that follows three very different Chicago families as they journey toward hope and healing after a tragedy connects them all. On the north side of Chicago, Daniel Calder is a high school history teacher mourning the death of his husband, an African American doctor who was shot by a white cop. As Daniel tries to comfort their grieving daughter, Jira Calder-Brennan, the two butt heads when she decides to search for her birth mother against his wishes. Daniel seeks comfort in his colleague – and Jira’s teacher – Liam Bhatt. On the south side, Tia Young scours news of the shooting, torn between her political ambition of running for alderman and risking it all to comfort the daughter she gave up for adoption as a teen. Tia’s husband, Ethan Young, a red line train operator and devoted father to their 6-year-old son, champions her running for office, but cautions her about connecting with Jira. On the west side, police officer Paul Evans is horrified that he shot an innocent man, conflicted about the circumstances around how it happened and worried about the public and legal fallout. His police partner, Victoria “Vic” Renna, whose loyalty may have driven her to go too far to protect him, and his brother, Jim Evans, a volatile former cop confined to a wheelchair after being shot in the line of duty, may cause more harm than good in their attempts to help him. As the stories of the Calder, Young and Evans families converge, a positive message surfaces: it’s possible to emerge from tragedy stronger than before, and it’s important to come together with others, not just to survive, but to thrive.

Ava DuVernay executive produces with Greg Berlanti and Sarah Schechter, as well as Parrish and Weiss. Stars include Emayatzy Corinealdi, Noah Wyle, Howard Charles and Aliyah Royale.
