Groove

Midwest transplant and aspiring novelist David Turner (Hamish Linklater) is an overworked recluse who writes computer manuals. One Saturday night, his brother Colin (Denny Kirkwood) invites him to a secret rave at a San Francisco warehouse. David reluctantly agrees and is shocked when Colin proposes to his new girlfriend, young raver sprite Harmony (Mackenzie Firgens). In the ensuing celebration, they take Ecstasy and David is thrust into the world of the San Francisco underground. His chance connection with longtime raver Leyla (Lola Glaudini) awakens in both of them a long-lost sense of possibility in their lives. But as the party rages on, Colin reveals a secret that threatens his relationship with Harmony. When the sun rises, the party disappears, but the last 12 hours has changed the two brothers forever.
