Knockdown

When the detective who investigated Beckett's mother's murder is shot before her eyes before he can give her new evidence in the case, Beckett's old wounds are reopened. The investigation of the detective's death leads the team to a group of three corrupt cops who were kidnapping mobsters for ransom until they accidentally shot and killed an undercover FBI agent. Johanna Beckett discovered the scheme while researching an appeal on behalf of the mobster who was charged with the death of the dead agent.
