Solitary, nostalgic Liz Crane returns to her family`s now-deserted farmhouse to study the migratory habits of the Monarch butterfly. A rich family history - all the anecdotes and blarney of successful Irish immigrants - is now tainted with sadness. Her cousin Amanda, a gifted military strategist, has been killed in Afghanistan, a loss foreshadowed by the earlier disappearance of her charismatic father. Reflecting on the fragility and transcience of human life and relations - mirrored in the Monarchs` restless flight - Liz finds that love is there to be found where you least expect it.
