Harry's family gathers in a bedside vigil as, unconscious after his car crash, he suffers from horrifying dreams of his father and his desertion. As word spreads of his accident at Selfridges, a somber mood oppresses the staff, compounded when they learn that Mr. Grove's invalid wife has died. Nevertheless, the grieving Mr. Grove comes to work, where an anxious Miss Mardle sees that he’s not ready to return.
Frank penetrates a pack of news hounds outside Harry's house, where he visits with his friend and tells Lois that Harry had been gambling and drinking the night of the accident. He also reveals that Ellen came to see him at the club.
While all this is going on, news circulates of an upcoming suffragette demonstration the next day in London. Everyone from the Selfridge daughters to the staff is wondering whether the suffragettes will come to the store. Miss Ravillious sees a suffragette leaflet that Agnes was given and reveals that she was at one of the recent demonstrations. Agnes, meanwhile, endures teasing from Kitty about how much work she has been doing for Henri. Her erstwhile suitor, Victor, is late for work -- he's in bed with Lady Mae.
Harry is hallucinating about his father, his disturbing fits worrying Rose, though the doctor indicates that Harry seems to be responding well. When discussion with Lord Musker turns to the store's succession plan if Harry dies, she says that their son, Gordon, would take over. They don't know that the boy overheard them.
At present, though, it's Mr. Grove who's holding down the fort, addressing the heads of departments at an emergency meeting. Understandably, Mr. Grove is having trouble managing the many decisions that need to be made, particularly concerning the pending suffragette march. When Miss Ravillious states that they can't just ignore it, and Mr. Perez points out that the suffragettes are to lunch at the Palm Court on the day in question, Mr. Grove tells him to cancel their table. It falls to Victor to tell Lady Mae that the suffrage lunch is off. Furious, she heads to Selfridges to urge Mr. Grove to reconsider his decision. But he sticks to his guns, and she to hers, warning that she can’t be responsible for the militant actions of some of the women.
Meanwhile, Frank visits a desperate Ellen at the Gaeity and urges her to move on from Harry. When she threatens to sell her story about Harry to the papers, he calms her by steering her toward a respectable future in theatre, where she can leave the dance halls behind.
As Selfridges' heir apparent, Gordon ventures to the store and is mistaken for a pickpocket! Agnes and Henri recognize him as Harry's son and tell Mr. Crabb that they’ll see him home safely. Thrown together in their care, Henri and Agnes discuss babies and her love life. He reveals that he’s interested in someone but doesn’t want to make a move. Agnes senses that he may be talking about her.
Mr. Crabb, aware that the time has come for him to take control, calls a secret meeting behind Mr. Grove's back to address the suffragette 'situation'. Believing that Mr. Grove's decision is going to backfire, he asks staff to stay late and work on a special window display, as Harry wouldn’t want the store to look to be anti-suffrage.
Finally, Harry wakes, weak but insistent that he return to the store. Against the doctor's orders, he heads to Selfridges and is caught up in the demonstration, now in full swing. Tensions rise, the militant suffragettes ready to trash the building, and he panics at what position the store leadership took in his absence. But the curtains then sweep open, revealing the windows created in homage to the cause just in time. Overwhelmed, Harry collapses amidst the chaos. It's his daughter Violette who rushes to his aid. A suffragette herself, she proudly tells the rest of the crowd exactly who the man is: her daddy, Harry Gordon Selfridge!
