Perfect couple Oliver and Lucy are getting married, but boastful best man Vince is appalled when he discovers that the groom has only ever slept with his bride-to-be. On the stag night, Vince pays escort Kim to introduce Oliver to the fabled pleasures of the Viennese Oyster Position. But when a text goes astray and Lucy shows up in her wedding dress, pimp Tony tries to recruit her to his sleazy agency. Unfulfilled Oliver hurriedly dresses, leaving would-be stud Vince to fail dismally in the sack with Kim. THE OYSTER POSITION is a salutary story about settling down, sex and seafood.
Stag night shenanigans ensue when the best man turns out to be the groom's worst enemy.
