The postables find a 200-year-old valentine that could change history, while each one deals with a heartbreak outside of work. Starring Eric Mabius, Kristin Booth, and Yan-Kay Crystal Lowe.

As with most of the Signed, Sealed, Delivered installments, this film covers four different stories woven together. We have the 200-year-old valentine that may or may not be about Abraham Lincoln; then we have the more current letter that is 15-years-old, and we have two couples in the postables having their stories told. The combination of the stories can sometimes be murky as they mix with the postable stories. This film does a good job of mixing the four stories together, and the acting is better than it has been in previous films. This film is worth a watch.
