|“||Don't be afraid. I'm a nurse.||„|
|~ Rachel Summers|
Rachel Summers is the stepmother of Anna Ivers who distrusted and hated her, and the main antagonist of the 2009 horror remake The Uninvited.
She was portrayed by Elizabeth Banks who played Rita Repulsa in the 2017 film Power Rangers.
Anna has been in a psychiatric institution for 10 months, following her suicide attempt after her terminally-ill mother died in a boathouse fire. Now she is being discharged and has no memory of the actual fire, although she is frequently plagued by nightmares from the night. While packing, Anna is startled by a talkative patient who asks, "Now who will I tell my stories to?". Shortly after, she leaves with her father, Steven Ivers. While driving home Steven tells Anna that his book is finished and had the names of Anna and her sister in it.
At home, Anna reunites with her sister, Alex. The sisters are very close, and they are united against Steven's girlfriend Rachel, who had been their mother's live-in nurse. Alex criticizes Steven for sleeping with Rachel while the girls' mother was still alive, but her comments fall on deaf ears. Anna describes to Alex how scenes from her dreams have started happening while she is awake. The sisters become convinced that the dreams and hallucinations are messages from their mother, telling them that she had been murdered by Rachel.
Anna catches up with her old boyfriend Matt, who tells her that he saw what happened the night of her mother's death. Later, the two secretly plan to meet, but he inexplicably fails to show up. Then, Anna awakens to find him climbing into her window. He says she needs to know the truth: that he had a warning from her mother. Suddenly, his body grotesquely warps, his back breaking. Anna runs from the room in fear. The next morning, Matt's dead body is pulled out of the water, his back broken just the way Anna saw it.
After the sisters are unable to find a record of Rachel with the State Nursing Association, they conclude she is actually Mildred Kemp, a nanny who killed the three children she was paid to care for because she had an obsession with their widowed father. They try to warn their father, but he brushes off their concerns and leaves for work. In desperation, the girls try to gather evidence against Rachel to show the police but Rachel catches them and drugs Alex using the sedatives from her nursing job. Anna manages to escape and goes to the police station, but they are disbelieving of her claims and call Rachel to take her home.
After Rachel puts Anna in bed, Anna sees Alex, no longer sedated, in the doorway with a knife, and passes out. Anna wakes shortly after to find that Alex has killed Rachel, and thrown her body in the dumpster. Relieved, the girls comfort each other. When their father drives up, horrified at the scene, Anna explains that Rachel tried to murder them but Alex saved them by killing Rachel. Confused, Steven tells Anna that Alex died in the fire. Anna looks down to find that she is not holding her sister's hand, but the bloody knife used to kill Rachel.
It's then that Anna finally remembers what happened on the night of the fire: After catching her father and Rachel together having sex, Anna filled a watering can from a large gasoline tank in the boathouse and carried it toward the house, intending to burn it down. However, she spilled a trail of gasoline that ignited when a candle fell over. Her mother was killed in the resulting explosion, as was Alex, who was also in the boathouse. It is revealed here that Anna has symptoms of both severe schizophrenia and dissociative identity disorder. Flashbacks reveal that Alex was never actually there throughout the entire movie, only being imagined as alive by Anna. She also remembers that Matt really did show up as planned, but she killed him by letting him fall into the water and break his back. It is revealed that Anna did indeed kill Rachel.
The police are called to arrest Anna for murder, and when Steven is questioned, he reveals that Rachel (real name: Rachel Worshitsky) changed her last name years ago to escape an abusive boyfriend, explaining why her name was not found on file when Anna called the State Nursing Association. The police ask why Anna would make up the Mildred story, but Steven remains speechless.
At the mental institution, Anna is welcomed back by the patient that scared her earlier, whose name plate on the door says "Mildred Kemp," implying that Anna's delusion came from actually knowing the real Mildred Kemp.
- She is based on the character Eun-joo from A Tale of Two Sisters.
