Cooke is sure Bruno Lubas killed policewoman Jo Keating, his enquiries leading to Lisa Wilson, who witnessed the original shoot-out and hid Bruno's gun, a service she supplies to other gun owners However Nikki and Jack suspect that Bruno has been framed and this seems surer when he is found shot dead, his death made to look like a suicide. Whilst Jack stumbles on an illegal gun trade involving an unlikely culprit it becomes obvious that the real killer is attempting a cover up of their own, putting Jack's life at risk as he goes after them.
