With each passing episode, the plot of Shadowhunters is thickening and 18-year-old Clary Fray, a human with angelic blood, is learning shocking facts about her family. Her frantic search for the Mortal Cup is making her realise the powers she has and episode 7 titled Major Arcana will feature her adventurous journey to the underworld in order to save her mother, Jocelyn.

Apart from the Mortal Cup hunt, Clary's friend Simon Lewis has some vampire issues to deal with. In the previous episodes, he was kidnapped by a bunch of vampires but was later rescued by Alec and Jace. But the after-effect of the kidnapping saga is turning Clary's human friend into a vampire. Even the description of the upcoming episode hints that the symptoms Simon is experiencing are really bad.

The official synopsis of the upcoming episode reads: After piecing together the clues as to where her mother hid the Mortal Cup, Clary, Jace, Alec and Isabelle are on the clock to find its hiding place before anyone else. But with demons and Downworlders lurking everywhere, obtaining the Cup may not be as easy as they had hoped.

Meanwhile, as Simon's symptoms become increasingly worse, he fears he is turning into a vampire.

In the previous episode, an injured Luke informs Clary that she had a brother Jonathan Christopher. But he died due to a fire caused by her father and the show's main antagonist Valentine. He asks her to find the hidden clues in order to get close to the cup, which is key to finding her mother who was kidnapped by Valentine, who has gone rogue.

By the end of the episode, Clary regains flashes of her memory and realises that she knows the location of the Mortal Cup. But her journey will not be easy as she needs to face the demons and Downworlders before reaching her destiny.
