What to know about the twisted ending of Zoë Kravitz’s new thriller ‘Blink Twice,’ starring Channing Tatum

Slater is initially presented as a charming billionaire who credits therapy with changing his life. But his sadistic behavior becomes clearer later in the movie.

After Jess gets bitten by a viper one night, she decides she’s had enough of the island. But Frida has no desire to leave because, for the first time in her life, she’s not invisible. The next day, Frida wakes up and goes about her typical routine: spraying herself with a perfume made from a red desideria flower found only on the island, getting dressed in the same white outfit, and joining the rest of the group for another day of relaxation.

When a maid gives Frida a green liquid to drink that’s actually snake venom, she begins to regain fragments of memories. Another guest on the island named Sarah (Adria Arjona) then confides in Frida and says she’s having a good time but also has a weird feeling that something’s off — especially considering that none of the women besides Frida have any memory of Jess, who vanished without explanation.

Frida and Sarah figure out that the perfume is erasing the women’s memories and that snake venom is the key to remembering. To help the other women regain their memories without raising suspicion, Frida and Sarah give them tequila shots mixed with venom. Stacey (Geena Davis), Slater’s scatter-brained assistant, also takes venom-laced shots with them.

Frida and Sarah then walk toward Slater’s compound — where he’s barricaded himself, Vic, and Lucas (Levon Hawke) inside — armed with a knife and a gun. As Frida enters the building, Sarah shoots Lucas from a distance and kills him instantly.

While fighting Slater, Frida regains more memories, revealing that she got the scar on the side of her face (which Slater had previously asked her about) after an incident in the woods with Slater during her previous visit to the island.

Slater ties up Frida and tells her that there’s no such thing as forgiveness, there’s just forgetting — and Frida is amazing at forgetting, as she forgot the island entirely after her last visit. He also says the world would be better if people were freed from remembering things.

Slater also implies that he and his sister were molested by an older male. This is presumably the traumatic event that happened to him before he was 10 and caused him to have few memories of that period, as he mentioned to Frida earlier in the film.

Slater is interrupted by Sarah entering the compound, and he runs after her, leaving Frida on the floor.

Slater drags Sarah into the room where Frida, who cut herself free using a glass shard, is holding the knife. Slater grabs her knife and Frida thinks he’s going to kill her, but he says he won’t because she’s his best friend.

As Slater is about to cut Sarah’s throat, he takes a hit of his vape pen and suddenly becomes disoriented. It’s revealed that when Frida freed herself from the ropes, she also laced his vape with the memory-erasing perfume he’d been using on the women.

Slater trips and falls over, knocking over some of the candles and causing a fire to spread. Before the compound fully goes up in flames, presumably finishing off a severely injured Vic, Frida and Sarah pull Slater out.

“I need a vacation,” Frida tells Sarah.

Frida gets what she wants in the end.

The last scene is a full circle moment for Frida, who’s no longer invisible. Instead, she’s in a powerful position and isn’t subservient to a man.

“I wanted to see a story that explored what might happen if women stop playing by the rules,” Kravitz wrote in a statement included in the production notes for “Blink Twice.”

Kravitz, who grew up in Hollywood thanks to her parents Lenny Kravitz and Lisa Bonet, said that she’s seen, experienced, and heard about things that inspired her to make a film about the dynamics between men and women. Kravitz added that the movie isn’t about any particular person.

“This is about people,” she wrote. “Women are being told to smile, every day, all the time. We are expected to ‘forget’ moments of discomfort, terror, and abuse and to keep pretending we are having a good time. We are expected to play the game.”

The movie ends on a well-deserved note for Frida, who’s fully in control and calling all the shots while Slater has become her head-empty puppet.

“This is not a story about empowerment,” Kravitz said. “This is a story about power.”

“Blink Twice” is in theaters now.
