It's the last days of summer. Best friends Seth and Jameson are getting ready to perform and party at local rock venue The Alamo.
But before the night begins, both young men come face- to-face with serious reality checks: Seth receives life-changing news from his girlfriend Mel, and Jameson has to choose between his on-again-off-again girlfriend Corin and a new girl he's just met, the outspoken Harmony.
At the show, Seth and Jameson's friends are too caught up in their own lives to be much help: young rocker Taylor romances his new crush Dana, and awkward Jack Rabbit avoids his childhood friend Lexi after learning what she did at her sister's wedding.
These intertwining friend-dramas, fueled by a lot of drinking, unfold against a backdrop of live music performed by the best bands in town. By the end of the night, these young men and women are confronted with a series of fast- approaching life decisions that will either leave them stuck in the comfort of adolescence, or catapult them into adulthood.
