When unfeasibly rich engineer Sam Prentis loses his genitalia to a rogue Rolls Royce sprocket, he is sold on the idea of a prosthetic phallus by the unfortunately named Richard Edwards, A K A Dick Ed. To inherit a fortune, Richard and Sam's gold-digging wife load a bionic replacement with liquid nitro. It's primed to detonate during aphrodisiac enhanced copulation, but something goes terribly wrong, or right, (depending upon who's looking at it.) Either way they are both in deep trouble.
To add to their woes, a high-octane sample has been mistakenly dispatched to Annie's adult shop in Glasgow: they take off to disarm the phallic time bomb before it is unwittingly sold on.
Glasgow pot-heads Tam and Jeddah, have made their weekly cannabis 'top up' trip to Bongo Bill's. After the proverbial pound shop munchies, via a trip to the offy, the rescue of a tailors' dummy from a builders' skip sets in motion a string of unstoppable events. How could they have known that such a random act of opportunism would take them to the Bahamas and change their lives forever?
