Twin sisters Molly and Marietta Helfing are eagerly anticipating Christmas, with Marietta fully re-covered from cancer and their noodle making business thriving. But Molly clearly misses having former tenant Pete Shetler and his rambunctious dog, Riley, around. Marietta can't ignore Molly's feelings for Pete--or the anxiety it stirs within her.
