Neighborhood Deal (2010)

Trent, Matthew, and Luis are three 19-year-olds making a movie on a summer day. After the trio learns of a big house party taking place later that night, they all get ideas: Trent sees potential for on and off-camera debauchery, Matthew sees production value for his movie and Luis just sees liabilities. When they learn they're supposed to bring whiskey to the party, they enlist Marshall, a stranger, to bypass that obstacle. However, Marshall will only relinquish the liquor if he's allowed to help out with the movie. Marshall's presence leads to annoyance, ultimately giving way to concern as he seems determined to prevent the trio from getting to the party.
