Lucy Stanbridge is a young publisher who inherited her father's once successful publishing house. To keep it afloat in face of a recent streak of disastrous releases, she seeks the help of cantankerous old writer Harris Shaw, a legendary author who hasn't published a book in 50 years. Lucy has a contract that stipulates Shaw still owes the publishing house a book and is required to do a book tour for it. Reluctantly, Harris agrees to gives his unpublished manuscript to Lucy and to go on tour with her, but his wild antics prove to be hard to handle.
