Locked up in the brig of the “Mariana” by Baronet Roshental, Sandokan and Iniko think up a plan to escape the noose waiting for them on land. Sandokan persuades the sergeant guarding them to let him see Mariana for the last time before he dies. Mariana goes down to the brig accompanied by the sergeant. Sandokan manages to tell Mariana of his plan of escape: she must fetch some herbs which Sandokan has in his cabin and send them to him in his food. The effect of the herbs is to stop the heart beating, making the person who has taken them appear dead. When the men on the ship see that Sandokan and Iniko are dead, they will throw the bodies into the sea. Mariana will throw life belts and knives down to them.
