The Staircase

In 2001, Kathleen prepares for a Christmas to remember despite the family's ever-mounting financial woes. Years later, Sophie continues her quest to prove Michael's innocence after a body with similar injuries to Kathleen's arrives in the county morgue. Meanwhile, questions about the state's justice system surface that could turn the tide of the Peterson case, and Martha decides to dig into her fraught past, despite pushback from Margaret.
