Between Shanghai and St. Pauli (German: Zwischen Schanghai und St. Pauli, Italian: I rinnegati di Capitan Kidd) is a 1962 West German-Italian crime adventure film directed by Roberto Bianchi Montero and Wolfgang Schleif and starring Karin Baal, Joachim Hansen and Horst Frank.
A violent bar fight leads to Carlos, Blacky and Jochen joining the crew of the ramshackle freighter 'Trinidad'.
It turns out that the decrepit ship with its expensive cargo is about to be blown up as part of an insurance fraud devised by the unscrupulous criminal Frederic and his accomplice Diana.
During a scuffle to capture Diana and Frederic, the criminal mastermind is able to detonate an explosive device attached to the ship.
The freighter sinks, but the three friends and Vera Anden manage to make it ashore, where the rogue couple is taken away in handcuffs by the Moroccan police.
