Brendan Quillian, a successful young businessman, is on trial for murdering his wife, and the courtroom is tense. Prosecutor Alexandra Cooper's case against him hangs by a thread thanks to scant evidence and Brendan's all-star legal team. As the trial progresses, an explosion destroys a water tunnel being constructed deep beneath the city. Then, secrets from Brendan's past link him to the fatal disaster. Alex rushes to the scene to scour the wreckage for anything that could help prove that this man has a history of violent, perhaps homicidal behavior and bring justice to a murdered young woman.
