A place of incredible, almost mystical beauty, where the grandeur and tranquility of nature sharply contrast with the brutality and tragedy of a committed murder.
On the frozen shore of Baikal, the body of former American diplomat Edwin Ashford is found, killed by a single professional knife stab. Money and personal belongings are untouched. No traces — none.
This mysterious crime threatens to escalate into an international scandal, as it pits Russian and American intelligence agencies against each other. An independent expert, Drongo — a brilliant analyst with a phenomenal memory — and pragmatic FBI agent Joan Crossman, sent from Washington to oversee the process, are brought in to investigate.
It turns out that everyone who knew Ashford has something to hide: his secret lover turns out to be the prosecutor's wife, his ex-wife — a CIA agent… As they unravel the tangled web of infidelity, broken lives, and secrets of the 'cold war,' the investigators try to understand: was this murder a political act or a delayed, horrific revenge for a tragedy thirty years ago, born in a ruthless intelligence struggle…
Some wounds do not heal but turn into a sentence.
