'There's a body! Down by the bridge!'

It's November 1900 in rural Hope Bridge, New York. The town is bustling with the chaos of construction workers, steam engines, and horse-drawn wagons as a new iron trestle rises over the Duncan Creek. Amid the clamor, the body of the bridge builder is discovered, plunging the community into shock.

Undertaker Carrie Lisbon is once again summoned by Sheriff Delphius Morgan to act as his 'keen observer.' She has a knack for solving the problems of the dead. She's good at what she does: embalming and laying out bodies, arranging funeral flowers, taking mortuary photographs, and keeping big secrets buried deep.

With Election Day just a week away, Carrie and Morgan's unconventional partnership is targeted by Morgan's rival for sheriff, a slick interloper who's running a dirty campaign, and thinks there's more to Carrie and Del's relationship than just a dead body. As if a murder case and political turmoil isn't enough, Morgan's teenage son, Eddie, goes missing.

When Carrie teams up with Morgan's steadfast deputy, a scrappy kid from the town dump, and an unlikely ally, they tease out clues to the murder while they search for Eddie. But as personal and political pressures mount, and she gets closer to identifying the killer, those big secrets threaten to become unburied, and Carrie has to make some hard choices to keep them where they are.
