In keeping with the original series, in the initial episode Hopkirk is murdered during an investigation and returns to Earth as a ghost tied to his partner Randall. Randall is the only living main character who is able to see him (though occasionally other characters can). The remake paid much more attention to where Hopkirk went when he was not on Earth than the original and introduced Limbo, a place where he could meet other ghosts. It also introduced the character Wyvern, a mentor who helps Hopkirk hone his powers, introduces him to other ghosts, and is terrible at poetry. The remake also made Jeannie a more central character than the original and changed her status to Hopkirk's fiancée, rather than widow, allowing for a love-triangle element between the three main characters to form.
