Jim "Lucky" Moore (Allan Jones), an insurance salesman, comes up with a novel policy for his friend, Steve (Robert Cummings): a 'love insurance policy', that will pay out $1-million if Steve does not marry his fiancée, Cynthia (Nancy Kelly). The upcoming marriage is jeopardized by Steve's ex-girlfriend, Mickey (Peggy Moran), and Cynthia's disapproving Aunt Kitty. The policy is underwritten by a nightclub owner, Roscoe (William Frawley), who sends two enforcers - Abbott and Costello - to ensure that the wedding occurs as planned.

How to Watch One Night in the Tropics Legally and Safely

If you want to stream One Night in the Tropics through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry One Night in the Tropics films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
