The Guilty S01E01 - Episode 1

The investigation into a little boy's disappearance is seen across two timelines: In 2008, when he vanished from a neighborhood barbecue; and five years later, after his body is found in a communal garden not far from his home. DCI Maggie Brand, who initially handled the case in 2008 before health reasons forced her to step down, takes control of the investigation.
