Called a "gripping action tale," the script was co-written with Adi Hasak ("From Paris With Love"). Here's the long-form synopsis which adds a few new wrinkles:
The thriller explores a story about Secret Service Agent Ethan Runner who discovers he's dying and decides to retire in order to reconnect with his estranged family. But when the Secret Service offers him access to an experimental drug that could save his life in exchange for one last assignment, he soon finds himself trying to juggle his family, his mission, and the drug's hallucinatory side-effects.
The deal marks the second of two films that EuropaCorp and Relativity will collaborate on as a part of a co-production and co-financing deal that was announced in May. That second picture is the darkly comedic action film "Malavita" directed by Besson and starring Robert De Niro, Michelle Pfeiffer, Tommy Lee Jones, Dianna Agron ("Glee," "I Am Number Four") and John D’Leo ("The Wrestler," "Wanderlust").
