Question: Build a movie plot around this: which scene depicts a fully aware aaron? The film's final scene
Answer:
Four engineers- Aaron (Shane Carruth), Abe (David Sullivan), Robert, and Phillip who work for a large corporation during the day, run a side business from Aaron's garage at night, building and selling JTAG cards. With the proceeds of this work they fund pet science projects that they hope will yield applications sufficient to attract "VC attention".After arguing over the project that the group should tackle next, Aaron and Abe independently pursue work on technology intended to reduce the weight of an object. Although the device seems to work as planned, it has a side effect: a timepiece left in the device shows the watch has experienced about 1300 times the amount of time the device was activated for. Abe reasons that they have created a time machine.After some testing, Abe secretly builds a prototype machine large enough to hold a person and, after traveling back to earlier that day, details the results to Aaron. Abe and Aaron build an additional machine (subsequently called "the box") and decide to cut Robert and Phillip out of the discovery, under the false pretense that the garage has to be fumigated.Abe and Aaron starts using the time machines to make money in the stock market, but as their understanding of how the machines work evolves, they become more adventurous with their trips. Their experimentation is cut short by the unexpected appearance of Thomas Granger (Chip Carruth), the father of Abe's girlfriend Rachel, whose financial backing the group had been trying to procure. Granger's trip appears to have made him comatose, and neither understand how Granger could have discovered the box. Abe is particularly disturbed by this turn of events and concludes that time travel is too dangerous to continue. He attempts to prevent his past self from using the machine for time travel, thereby nullifying all of its consequences, by using a "failsafe" machine, which he previously built in secret, to travel back to a point prior to his first trip through time and also prior to his broaching the subject of time...
