The titular panther embarks on a series of comical escapades on Valentine's Day.

On Valentine's Day, the Pink Panther, feeling lonely and nearly broke with only seven cents, seeks a job at a messenger service, but his initial audition goes awry. Undeterred, he uses his remaining seven cents to purchase a cassette player and pre-recorded cassettes, then returns to the messenger service, where his unique miming of "Vesti la giubba" secures him the job. Throughout his adventures as a messenger, he becomes embroiled in humorous situations involving a jealous husband, a snobby violinist, a confused priest, and a crime boss, culminating in a showdown where he thwarts the criminals using a cassette tape with police radio excerpts. Finally, his eventful day leads him to meet the pantheress of his dreams, completing the charming Valentine's Day tale.
