PROJECT ALMANAC 

Project Almanac(formerly titled Cinema One, Almanac, and Welcome to Yesterday) is a 2015 American found footage science fiction thriller film directed by Dean Israelite and written by Jason Harry Pagan and Andrew Deutschman. Filmed in 2013 and originally planned for an early 2014 release, the release date was later moved to January 30, 2015.

PLOT:

in 2014, 17-year-old high school senior and aspiring inventor David Raskin (Jonny Weston) is admitted into MIT, but is unable to afford its tuition. Upon learning his mother, Kathy Raskin (Amy Landecker), is planning to sell the house, David enlists his sister Christina (Virginia Gardner) and his friends Adam Le (Allen Evangelista) and Quinn Goldberg (Sam Lerner) to go through the belongings of his father, Ben Raskin (Gary Weeks), an inventor who died in a car crash on David's 7th birthday, in the hope of finding something that David can use to get a scholarship. David ends up finding an old camera with a video recording of his birthday, in which he briefly spots his 17-year-old self in a reflection. The four later find the blueprints of a temporal relocation device that Ben was developing for the United States military, and use the available resources to build a functional time machine, including hydrogen canisters stolen from their school. David, Christina, Adam, and Quinn later use the battery from the car of David's longtime crush, Jessie Pierce (Sofia Black D'Elia), who is attending a party in the neighborhood, to charge up the machine, and successfully send a toy car back in time. They end up being caught by Jessie and recruit her to their experiment, which they nickname "Project Almanac."

David, Jessie, Christina, Adam, and Quinn eventually travel back in time to the day before and break into Quinn's house, where they draw a smiley face on the back of the neck of a sleeping past Quinn (which simultaneously appears on the back of the visiting Quinn's neck). However, he awakens and seeing his future self nearly erases them both from the timeline. The five agree to use the machine for personal gain on the condition that they always use it together. Adam uses it to win the lottery, Christina gets back at her bullies, Quinn aces a chemistry test to secure his academic future, and the group eventually decides to travel back to Lollapaloozathree months before. David hesitates to declare his feelings for Jessie, and decides to travel back in time alone to change that, leading to a future in which they are a couple. However, this creates a ripple effect that causes the school's star basketball player to have broken his leg and lose the championship, as well as a plane piloted by a classmate's father to have crashed, killing 77 people. David goes back alone once again and prevents the accident that would lead to the player's injury, and averts the plane crash. He returns to the future to learn that instead Adam is in critical condition in the hospital after being run over.

Jessie confronts David, who is forced to admit to using the time machine to win her affection. They travel back in time together to rectify David's mistakes and save Adam, but Jessie ends up running into her past self and is erased from the timeline, causing an even more devastating ripple effect, leading to worldwide catastrophes. David decides to go back to his 7th birthday to prevent the machine from being created, but is confronted by the police, who suspect him of being connected to Jessie's disappearance. David escapes to his school to use a hydrogen canister to return to 2004, where he is accidentally caught on camera.

At the basement, David confronts his father Ben, who recognizes him and deduces that he'll eventually complete the machine. David convinces Ben of the machine's danger and they destroy the blueprints and a vital circuit together, before David is erased from the timeline. However, his camera is left behind and records the whole thing. Back in the future, David and Christina are once again going through their father's belongings, when they find the alternate David's camera with footage of them from minutes before. Later, at school, David approaches Jessie for the first time once again, displaying knowledge of the future, and confides in her that they're about to "change the world."
