Something does not seem right between bride, Gretchen, and groom. None of their friends seem to fully support the marriage and have secrets of their own. Unresolved about their relationship and endlessly obsessed with the groom, Cole stirs up everyone and everything, making it a weekend to remember.

Ridesharing just got a whole lot scarier.
