The conclusion of Blacklight's exhausting Book of Days tour finds guitarist JP Kinkaid recuperating at home in San Francisco. As JP's local band, the Fog City Geezers, plans gigs at Marin County's 707 Club, the club is put up for sale. Blacklight, seeing an opportunity to preserve a classic venue, acquires the majority stake. But the minority ownership comes with strings attached. There are troubling questions about the source of the stake money. There's prickly, unpredictable promoter Norfolk Lind, whose son Curtis is romantically involved with Blacklight band baby Solange Hedley, now in cooking school in San Francisco. And Lind's partner, Esther Woodley, has some dark history of her own with JP's wife, Bree. The Geezers celebrate the opening of the newly refurbished 707 with a private show. But when the club is destroyed by arson, Blacklight's new security chief, retired homicide cop Patrick Ormand, must dig deep into the local music scene's murky past to find the truth.
