Writer Jacob Hastings is uninspired by his latest assignment: a museum full of hideous rocking horses. But his socks are rocked by Normandie Stephens, a mischievous astronomer who can match his dry wit, quip for quip, and his sexual appetite, frolic for frolic, with energy to spare. Thanks to Jacob's public relations and the machinations of a feisty and frisky mentor named Kate, an impasse in Normandie's career promises to blossom into either glory or disaster - with enigmatic photographer Susan and obtuse clubber Brandon along for the wild rocking-horse ride.
