A brilliant doctor resilient and dependable arrives with his wife at a conference in Europe, the two looking forward to innovative discussions throughout the upcoming thought provoking week (Liam Neeson as Dr. Martin Harris and January Jones as Elizabeth Harris).

But Mr. Harris forgets a suitcase at the airport and must return with improvised haste, a random accident then suddenly sending his swift moving cab into the river.

He wakes in the hospital four days later confused and uncertain of his identity, flashbacking memories intermittently bombarding his worried bewildered forlorn consciousness. 

Enough memories are pieced together to locate his wife back at the hotel, but she's claiming another man is her husband (Aidan Quinn as Dr. Martin Harris), and he has the credentials to prove it.

Dr. Harris A has no supporting documentation and is alone in a foreign city, his only contacts the irritated cab driver (Diane Kruger as Gina) and an old school Stasi agent (Bruno Ganz as Ernst Jürgen).

But as they help him piece things together determined hitpeople come viciously calling.

His life hanging in the chaotic balance.

If he can determine which life is his own.

Identities ephemeral consistent mutating sculpted and warped through variable circumstances, sincere lighthearted earnest scenarios generating alternative fluid trajectories. 

In Dr. Harris's case, a traumatic shock engenders tumultuous transmutations, childlike innocence serendipitously resuscitated with headstrong free contradictory will.

As if latent wondrous ethical senses habitually reside within unobstructed awareness, a less reserved curious luminous syndication ethereally materialized through pneumonic flux.

Divergent associates proceed reflexively according to malleable regenerative factors, expectations foiled with animate nuance or transformatively adorned with newfound resonance. 

New sets of variables present cherished fascinations as inquisitive impulses react with the arts, ahistorical multilateral syntheses composing flexible dynamic spectrums.

Acquiring new knowledge leads to the reinterpretation of staple favourites convivially collected, the reinvigoration of personal relationships, intricate staunch identity.

Dr. Harris makes a go of it in Canada and Québec as so many adventurous people do.

Not that anything's written in stone.
