Rachel Chavez, a recovering alcoholic, owns and lives in an apartment on the top floor of a parking garage in downtown Los Angeles. She leases parking space and the use of the rooftop helicopter pad to nearby businesses. Tough but vulnerable, she is struggling to stay sober and keep her business financially afloat.

Then things become very complicated. And dangerous....
