Women are being attacked and robbed whilst several businesses have been burgled. Are these two circumstances linked or is this just a coincidence? As the attacks escalate, and the police seem unmoved to intervene, the men of Dressmakers' Alley decide to take the law into their own hands and patrol the streets to keep them and their women safe. But when the man suspected of the attacks is found brutally murdered the eyes of suspicion fall on the group and Sam Collins is charged with murder. He seemingly has a motive, no alibi and is the owner of the murder weapon. The Police are convinced they have their man but fiancé Winnie is determined to prove him innocent. When the mystery comes to a head, a dark and surprising secret is revealed. The selfless action of a father prevents a miscarriage of justice - but at what cost?
