All aboard the Valentine's Train... Mira James's budding relationship with boyfriend Johnny is definitely warming up her winter. But when Johnny is offered an internship he can't pass up in Portland, Oregon, Mira lets Mrs. Berns talk her into a visit. On the plus side, Mira will be able to take the trip as a tax write-off by attending the International Private Investigator Conference that happens to be going on at the same time. The only drawback for airplane-averse Mira is that Mrs. Berns has booked them on the Valentine Train-a route designed to help singles meet and mingle. Relaxing into the experience with a few glasses of champagne and Mrs. Berns's encouragement, Mira begins to enjoy herself...until a fellow passenger is murdered.
