The drug market under double siege Undercover policeman Martin and Zdravko-Kosama have to deliver a ton of benzyl methyl ketone (BMK) - an ingredient used in the production of amphetamines. However, the two are deceived by the dealers who supply them with another substance. At the same time, the police set a trap for them and Jaro's employees are taken into custody, from where they are surprisingly released. It turns out that instead of the BMK ingredient, the dealers sold them epoxy resin, which is a substitute. Martin and Kosama's task is to find the crooks and return the goods, without which Jaro's big deal with amphetamines fails. In the meantime, the police are preparing an action against the person whose property is the workshop producing the illegal ingredient. Will Martin and Zdravko be able to outrun the police and correct their mistake in time? All they can do is fight back.
