Trying to remember a good indie movie I saw awhile back (~3-4 years ago). Science Fiction. Two buddies in their garage trying to build something for their startup company. Next thing you know, the device they're trying to build ends opening the possibility of using it as a time travel machine of sorts. So they place a copy of it in a storage garage, activate it in the morning, and at the end of the day jump in to replay that same day. Some interesting sub-plots grow from there, all the while trying not to destroy the space time continuum. It turns into a really cerebral movie where you have to figure out what timeline you are witnessing. Turns into a whodunit murder mystery too. Any ideas movie buffs?
