The city of Denver is experiencing a rash of mailbox robberies. Our intrepid four spring into action, determined to recover the stolen letters and help a young waitress retrieve a love letter she regrets having sent. Oliver is shocked to discover the perpetrator is a fellow postal worker with a personal score to settle. The postal detectives soon find themselves in a tense standoff when the culprit threatens to destroy the mail if his demands are not met. Along the way, romance slowly blossoms (too slowly for most of our POstables!) between the buttoned-up Oliver and Shane.
