Kimberly Williams-Paisley (“The Christmas Chronicles”), Tom Cavanagh (“The Flash”) and Wendie Malick (”American Housewife”) are back for the fourth installment of the “Darrow & Darrow” Hallmark Movies & Mysteries series and the first of 2019.

In “Witness to Murder: A Darrow Mystery,” which premieres on Sunday, Claire Darrow (Williams-Paisley) and her mom, Joanna (Malick), have to make a difficult decision when Joanna’s former mentee and friend, Cassie Piper (Elysia Rotaru, “Arrow”) comes to them for help.

“Cassie betrayed that friendship when she leveled the insider trading accusations the ended Joanna’s career – accusations Cassie later realized were faked by their corrupt bosses,” the synopsis shares. “Now those same attorneys have set Cassie up on felony charges of financial crimes, and the pending case has already cost her custody of her beloved daughter. Claire leaves the decision up to Joanna, who makes up her mind to take the case when her ex-boss Brian Herriman (Martin Cummins, ‘When Calls the Heart’) tries to buy her off with a job offer.”

The episode 4 synopsis continues: “But the Darrows’ task becomes much more complicated when an apparent attempt on Brian’s life leaves another man dead. Brian identifies Cassie as his would-be killer and there is powerful evidence linking her to the crimes. Could it be another frame-up? Claire and Joanna launch their own investigation into the incident and turn up a host of potential suspects. Meanwhile, Claire and D.A. Miles Strasberg (Cavanagh) navigate a tricky moment in their as-yet-undefined relationship as they prepare to face one another in court.”

Directed by Michael Robison and written by Phoef Sutton, “Witness to Murder: A Darrow Mystery” also stars (Lt. Sarah Lang), Barclay Hope (Raymond), Antonio Cayonne (Chester), Tosca Baggoo (Judge Batcheller), Vincent Dangerfield (Scott), Christie Burke (Tammy McMahon), Gelsea Mae (Zoey) and Lilah Fitzgerald (Lou Darrow).

Although “Witness to Murder: A Darrow Mystery” is part of a Hallmark Movies & Mysteries franchise, it will premiere on Sunday at 9 p.m. EDT on both HM&M and Hallmark Channel.
