Jordan Jaffe’s comedy-drama Whirlwind hinges on a hot topic: environmental activism. It’s also descriptive of the relationships at its center. Bethany Goodbridge (Annapurna Sriram) handles issues of environment, health and safety at Arrow Energy, a San Francisco firm that builds wind farms. Her boss, Cooper (Johnny Wu), is an arrogant corporate type who likes to brag that he has his own jet. He also has more than a businesslike eye on her. Christian Conn plays the man who brings the whirlwind into their lives and ruffles their feathers—an apt description, since he is irate that one of the company’s isolated wind farms is killing birds at a terrible rate.
