William makes his peace with his parents but assures them that his interest in developing steam engines supersedes his desire to inherit the shipyard. James's failure to listen to William results in the engine blowing on the ship he is using to take Polish emigrants to New York and he puts in to Liverpool for repairs. Maritsa, one of the emigrants ,is a talented lace-maker, and Robert wants to employ her in his sweat-shop but a sympathetic Samuel advises her she would be better off going on to New York. Unfortunately another accident with the steam engine leads to the ship lurching violently, trapping Maritsa's fingers in a door and requiring two to be amputated.
