Cal and Zoe (Jennifer Beals) are called to witness the execution of a man (David Marciano) they helped send to death row 17 years before—and face the possibility that he’s innocent. Marciano is joined in the cast by fellow alumni of “The Shield,” including David Rees Snell, Catherine Dent, Benito Martinez, Kenneth Johnson and Cathy Cahlin Ryan, the wife of “Lie to Me” executive producer (and creator of “The Shield”) Shawn Ryan.
