Much like the Goonies, Vikings never say die.

TV's most memorable finales

After last week's disastrous attempted raid on Paris, Thursday's Vikings will find Ragnar and his men carrying out a new plan to get through the walls of the fabled city. And in this exclusive sneak peek, Rollo (Clive Standen) seems determined to make up for getting almost fatally distracted by Princess Gisla (Morgane Polanski) by leading his own attack against King Charles.

(Though, keep in mind, historically, Rollo winds up marrying Gisla and converting to Christianity. So don't expect him to be able to resist Gisla for too long.)

Vikings airs Thursdays at 10/9c on History.
