Ta sainia (1982)

In the dead of night, the harmless but frightful apparition of a long-lost brother pays a visit to his petrified sibling, Pelopas, to reveal the phenomenal alchemical formula of converting urine into petrol. Five ordinary ingredients and a little supernatural guidance are all that's needed to go from rags to riches for life; however--as the friendly ghost starts dictating--a bitterly annoying and utterly catastrophic interruption leaves the precious list incomplete. But, just how difficult can it be identifying the final component? Could it be a liberal sprinkle of flour, a generous dash of one's favourite liquor, or is it something far more exotic?
