What happens when a father's sudden vanishing act nearly six decades ago opens a door to a sinister family secret buried deep within a quiet Long Island neighbourhood? Investigation Discovery (ID) is set to explore this harrowing question in a new documentary, The Secrets We Bury, that follows a family's relentless search for the truth about their long-lost patriarch.

The documentary unveils a cold case and the dark, unexpected turns of a family's past.

The film gives an intimate look into the Carroll family’s decades-long investigation following George Carroll’s disappearance, who walked out on his wife, Dorothy Carroll, and their four children in the late 1960s.

George’s son, Mike Carroll, becomes the main driver of the search, setting out to unravel the mystery of what truly happened to his father after all these years. This intensive pursuit ultimately uncovers a much darker family history than anyone anticipated.

The documentary features striking archival footage and extensive sit-down interviews with the Carroll siblings, spanning decades of their emotional struggle. As seen in the trailer, Mike recalls a neighbour handing his mother a box of his father’s belongings, sparking early suspicions.

When Mike later discovers this neighbour was actually his grandmother, he questions everything he thought he knew about his late mother and the secretive circumstances surrounding George’s vanishing.

The central figures are the siblings whose lives were dramatically shaped by their father's absence.

The main subjects of the documentary are the four Carroll siblings, notably George's son, Mike Carroll, whose determination drives the central investigation. The film relies heavily on their candid accounts and memories, alongside intimate archival footage that pieces together the family’s history.

The film features extensive, intimate sit-down interviews with the Carroll siblings, Patricia E. Gillespie, the director, and archives of Dorothy and George Carroll from their family life.

As per US Weekly, Jason Sarlanis, President of Investigation Discovery, noted that the family bravely sharing their story reveals how the past always has a way of resurfacing. The documentary promises to deliver equal parts chilling mystery and profound family drama, focusing on the lasting impact of generational trauma.
