Sisi - Season 4

Sisi has a serious riding accident on Corfu. To avoid jeopardizing her recovery, Franz hides from her that her father is dying. When she learns of Max's death, she travels to Possenhofen. There she discovers that her father has lost the family seat to jockey Georg Basselet of La Rosée in a horse race. Sisi asks for revenge, but the experienced rider will only agree if the Empress climbs into the saddle herself.

Although Franz has asked her never to ride again, Sisi begins to train secretly for the race against Georg. When the stable master Linda disappears, Sisi finds out that she is Max's illegitimate daughter and thus her half-sister. Meanwhile, Louis is offered the position of Minister of Justice. However, to do so he would have to give up his marriage to the opera singer Henriette. Meanwhile, Sisi's sister Sophie Charlotte is trying to win King Ludwig's heart.

Sisi has managed to persuade Linda to train with the temperamental Avalon and is finally making progress. While this also brings her closer to Georg, Henriette breaks off her inappropriate engagement with Louis so as not to endanger his position at court and as future Minister of Justice. Meanwhile, Sophie Charlotte is supposed to choose a marriage candidate at a festival in Possenhofen. King Ludwig suddenly appears and kisses her in front of everyone. While Sisi is secretly dancing with her betting opponent Georg, Linda's mother Adele, Max's former lover, is found dead.

The police have arrested Linda as the main suspect in the murder of her own mother. While Sisi tries everything to prove her innocence and asks an old acquaintance for help, Ludovika convinces Georg to call off the big race. Although Louis and Henriette have broken off their engagement, they cannot keep their distance from each other. And Sophie Charlotte is suffering from severe heartbreak because Ludwig has not contacted her since the night of the celebration in Possenhofen.

After an emotional night, Sisi is able to convince her rival Georg to keep the agreement to hold the race for Possenhofen Castle. Ludovika fears that Sisi will discover her long-kept secret and asks her sister Archduchess Sophie for help. Louis and Henriette decide to continue their relationship as a secret affair in order to secure their careers. Meanwhile, Sophie Charlotte breaks free from Ludwig. When Franz finds out about the horse race, he wants to bring Sisi back to Vienna.

Sisi is putting the last pieces of the puzzle of the great family secret together. She travels back to Bavaria to convince her mother to finally tell her the truth. Louis, meanwhile, is faced with the decision of having to give up his love for Henriette. And Sophie Charlotte gets to know King Ludwig's vulnerable side. Sisi finally defies Franz and takes part in the final horse race, thereby risking her husband's love.
