When a mysterious lawyer, Gina Hawkes (Thekla Reuten) turns up asking Harry to find a missing alibi witness for her client, he finds himself unwittingly drawn into investigating the death of his brother twenty years ago. But as he begins to untangle the web of lies and deceit, Harry finds himself caught up in a bigger and more complex conspiracy.
