Lucy Collins (Lucille Ball) saves up for a trip to Las Vegas to see her favorite singer, Dean Martin. Alas, the show is sold out. Lucy goes through her bag of tricks to get a table, but fails. When she hears that Dean does a special late show for hotel employees, she gets a job at the hotel (with predictable comic results). Finally, Dino hears of her plight, and invites her to see the show as his guest (and fly back to LA with him on his private jet).
