Things usually do not go as planned for seventeen-year-old Noah. He and his best friend Walt (aka Swing) have been cut from the high-school baseball team for the third year in a row, and it looks like Noah's love interest since fifth grade, Sam, will never take it past the best friend zone. Noah would love to retire his bat and accept the status quo, but Walt has got big plans for them both, which include making the best baseball comeback ever, getting the girl, and finally finding cool. Noah is reluctant, but fate intervenes when he discovers a gold mine of love letters from the 1950s. The letters initiate Noah into the curious rhythms of love and jazz. Soon, Walt's hitting balls out of the park, and Noah's composing anonymous love letters to Sam. But just as things have started looking up, the letters set off a chain of events that changes everything Noah knows to be true about love, friendship, sacrifice, and fate.
