Liam O'Leary is a very successful Dublin businessman, comfortable in his esteemed place in society, so when he finds a man is stalking him, his doppelganger no less, Liam is on edge, and when he finds out the man intends to replace him, not just in the corporate world but in every aspect of his life, he justifiably panics. 'The Tiger's Tail' is a clever and blackly comic re-interpretation of the 'Prince And The Pauper', and marks a timely, understated return to form for director John Boorman.
