The Adjustment Bureau

In 2006, Brooklyn Congressman David Norris unsuccessfully runs for the United States Senate. While rehearsing his concession speech, David meets Elise Sellas. They share a passionate kiss, though he does not get her name. Inspired by her, David delivers an unusually candid speech that is well-received, making him a favorite for the 2010 race.
A month later, David prepares for a new job. At Madison Square Park, near David's home, a man named Harry Mitchell receives an assignment from Richardson, his boss: ensure David spills coffee on his shirt by 7:05 AM so he misses his bus. Mitchell falls asleep and misses David, who encounters Elise on the bus and gets her phone number. David arrives at work to find his friend Charlie Traynor frozen in time and being examined by unfamiliar men. David attempts to escape, but is incapacitated and taken to a warehouse. Richardson explains he and his men are from the "Adjustment Bureau". They ensure people's lives proceed as determined by "the Plan", a complex document Richardson attributes to "the Chairman".[8][9] The Bureau confiscates and destroys the note that contains Elise's phone number, and David is warned that if he reveals the existence of the Bureau to anyone else, he will be "reset"âakin to being lobotomized. He is not meant to meet Elise again.
Three years later, after boarding a bus, David encounters Elise; he tells her he spent three years riding that bus to work, hoping to see her. He learns that she dances for Cedar Lake Contemporary Ballet. The Bureau tries to stop him from renewing their relationship by altering their schedules. David races across town, fighting the Bureau's abilities to "control his choices" to ensure he will meet Elise. During the chase the Bureau uses ordinary doorways to travel instantly to distant locations. Senior official Thompson takes over David's adjustment and takes him to the warehouse, where David argues he has the right to choose his own path.
Thompson says humanity received free will after the height of the Roman Empire, but then brought the Dark Ages upon itself. The Bureau took control after five centuries of barbarism, and created the Renaissance, the Enlightenment, and the scientific revolution; when free will was granted in 1910 it resulted in World War I, the Great Depression, Fascism, the Holocaust and the Cuban Missile Crisis, forcing the Bureau to retake control. Thompson implies that without Elise's influence David might become President of the United States, and warns that if he stays with her, he will ruin their futures. Thompson causes Elise to sprain her ankle at a performance to demonstrate his power, and David abandons her at the hospital to save them from the fate Thompson described.
Eleven months later, Charlie tells David of Elise's imminent wedding as he campaigns again. Harry contacts David via secret meetings in the rain or near water, which prevents the Bureau from tracking them. Harry reveals that Thompson exaggerated the negative consequences of David and Elise's relationship, and teaches David how to use doors to teleport and evade the Bureau's adjustments. Just before the wedding David reaches Elise, reveals the Bureau's existence to her, and shows her how he travels through doors. The Bureau pursues them across New York City. David decides to find the Chairman to end the chase, with Elise accompanying him. They enter the Bureau's offices with agents in pursuit.
David and Elise find themselves surrounded on the observation deck of the GE Building. They declare their love and kiss before David can be reset. When they let go of each other, the Bureau members have gone. Thompson appears but is interrupted by Harry, who shows him a revised Plan from the Chairman: one that is blank starting from the current moment. Harry commends them for their devotion to each other, then says they are free to leave. David and Elise walk down the street as Harry speculates that the Chairman's goal may be to prepare humanity to write its own "Plans".
