Set in San Francisco as the tech-boom is exploding, Bottle Grove is a sexy, skewering dark comedy about two unions--one forged of love and the other of greed--and about the forces that can drive couples together, into dependence, and then into sinister, even supernatural realms. Add one ominous shape-shifter to the mix, and you get a delightful and strange spectacle: a story of scheming and yearning and foibles and love and what we end up doing for it--and everyone has a secret. Looming over it all is the income disparity between San Francisco's tech community and . . . everyone else.
