Series premiere. Amid mounting community pressure, Detective Mare Sheehan shoulders a directive to revive an unsolved missing person's case.

Mare questions suspects in a grisly murder case and gives an icy welcome to Colin Zabel, a county detective called in to assist.

Phone records lead Mare and Colin to question an unlikely suspect. Later, Mare receives some unprompted family advice from Richard.

Colin presses a local priest about his past. An anonymous call gives Dawn hope that Katie might still be alive.

Mare meets with a semi-retired source about possible connections in her three cases.
