Christine Lahti has joined the cast of ABC’s new drama pilot The Adversaries, EW has learned.

The project, which hails from David Zabel, tells the story of a patriarch Charles Fisher (Terry O’Quinn) of a New York legal dynasty who becomes embroiled in a trial of his own, and his federal prosecutor daughter must decide which side she will fight on.

The Emmy-winning Chicago Hope alum, who appeared alongside O’Quinn on Hawaii Five-0, will play Katherine Fisher, Charles’ estranged wife.
