Session Girls gives the inside scoop on music producer Joli Nye (played by Lauren Worsham of A Gentleman's Guide to Love And Murder), bawdy backup vocalist Cocoa (Lesli Margherita, Matilda The Musical), classical cellist Mariana (Oyoyo Joi, The Book Of Mormon), and their trials and tribulations as they navigate the music world, their love lives, and unanticipated change. The subplot covers a harrowing major label / recording studio merger, helmed by Terrence Rand, who is smitten in a most gentlemanly way with his new producer, Joli, and by happenstance, in the uncomfortable position of calming his anxious theater producer pal, Mitchie Karabakis. Max Beft is a studio engineer enthralled with Cocoa, much to the chagrin of his fiancée Maya and her cousin, Celia Webb, an executive at the studio. Amid all this, cellist Rouald Finckel, fiancé to Mariana, is hoping for marriage, but Mariana isn't ready and has business plans with Delivery Guy. Cocoa's Nashville musician cousin, Lucinda, arrives with unbridled — if not unwelcome — enthusiasm.
