Das Herz von St. Pauli (1957)

Due to a lack of money, Hamburg pub owner Jonny Jensen brings two partners on board. As soon as the contract is finalized, the ex-sea bear is almost struck by a blow: the shady duo want to turn his quaint harbour bar "Herz von St. Pauli" into a demimonde pub with lingerie shows. Jonny can't let that happen!
