It’s been four years since Nick and Audrey Spitz’s (Adam Sandler and Jennifer Aniston) long-awaited honeymoon trip to Europe turned into an Interpol manhunt in Murder Mystery.

With the couple about to embark on another lavish getaway turned high-stakes adventure in Murder Mystery 2 on March 31, it’s time to reopen the case: How did the Spitzes unmask billionaire Malcolm Quince’s (Terence Stamp) killer? 

🤐 SPOILER ALERT 🤐

First things first: What is Murder Mystery about?

Murder Mystery begins with New York City cop Nick Spitz booking a last-minute trip to Europe for his wife, Audrey, after she confronts him about breaking the promise he made 15 years ago on their wedding day. On the plane over, a sneaky trip into the first-class lounge to steal some earplugs leads to a chance encounter with dashing British gentleman Charles Cavendish (Luke Evans), who invites the couple aboard his uncle’s yacht touring the Riviera. Oh, and by the way, said uncle is none other than billionaire Malcolm Quince, who happens to have just tied the knot with Cavendish’s former fiancée, Suzi Nakamura (Shioli Kutsuna). Messy, you say? We’re just getting started.

Who dies in Murder Mystery? 

Malcolm has gathered his nearest and dearest — in this case, son Tobey (David Walliams), actor Grace Ballard (Gemma Arterton), best friend Colonel Ulenga (John Kani) and his bodyguard Sergei (Ólafur Darri Ólafsson), business associate and maharajah Vikram (Adeel Akhtar) and race car driver Juan Carlos (Luis Gerardo Méndez) — to tell them that he’s cutting them out of his will. They’re getting zilch from that $70 billion payload. Instead, new wife Suzi will stand to inherit the lot. But before he can sign the new document, the lights go out. When they turn back on, Malcolm is — you guessed it — dead, stabbed with his own ceremonial dagger. 

So, who did it? That’s the question Nick and Audrey attempt to answer as the bodies start to pile up around them. (Malcolm’s murder is soon followed by Tobey’s, then Sergei’s, Suzi’s and finally, Charles’.) The problem is, they’re Interpol Inspector de la Croix’s (Dany Boon) prime suspects.

Who is the killer in Murder Mystery?

The quest to prove their innocence leads the Spitzes from Monaco to an opulent villa overlooking Lake Como where everything finally comes to a head. With no other leads to go on, de la Croix steps in to make his arrest, asserting that because the first murder occurred in French territorial waters, the Spitzes will be taken to Paris for prosecution. (“You always wanted to go to Paris,” Nick tells Audrey, a wink to the sequel, which finally takes the couple to the City of Love.) 

Audrey shares that under French inheritance law, each of Malcolm’s children would’ve received an equal share of his money, regardless of any provision in his new will. “But both of Malcolm’s children are dead,” she says. Wait, both? (See — messy.) You see, Sergei confided in the Spitzes before he died: Suzi isn’t the first fiancée Malcolm has stolen for a bride. Long ago, he married Colonel Ulenga’s intended, Madeleine LeBoutillier, while the former was in a coma, and she reportedly died giving birth to a son, who also died at birth. 

But what if the son was a daughter? And what if that daughter hadn’t died at all, but rather simply changed her name? An actor, perhaps? Like… Grace Ballard? 

Turns out, she was actually born Grace Butler — an anglicized version of her mother’s name, LeBoutillier. Determined to get back at the father who gave her away, she partnered with her half-brother, Tobey, to kill Malcolm and get the inheritance while on French territory, and then murdered the former to get the full amount. Ballard denies everything, but as Legally Blonde teaches us, to catch a killer, simply look at their hair. Why would Grace wear a hat over a freshly styled ’do? And hey, didn’t Nick hit the killer in the head with a plate? Said chapeau is lifted to reveal an angry cut, and after an altercation, Grace is taken into custody.

What’s the twist in Murder Mystery? 

Nick and Audrey’s celebration after solving the case is interrupted when Vikram realizes that Grace couldn’t have killed Sergei. That means she wasn’t working alone. And indeed, Juan Carlos is the one who masterminded the whole thing, convincing Grace to murder Tobey and carrying out the others himself. Why? To avenge his father, who lost both his legs after a racing accident he believes was caused by Quince. Cornered, Juan Carlos takes de la Croix hostage and speeds off, with Nick and Audrey in hot pursuit in a Ferrari. Employing a little creative driving, Audrey manages to make him crash, saving de la Croix. Juan Carlos pulls a gun, but is flattened by an oncoming tour bus — the very one Nick and Audrey were supposed to have been on this whole time. 

Where do we leave off with Nick and Audrey?

Riding high off their success as amateur detectives, Nick and Audrey finally resume their dream honeymoon trip — on Interpol’s dime — stepping onto the fabled Orient Express in a nod to the patron saint of murder mysteries: Agatha Christie. And where do they go from here? Find out when Murder Mystery 2 comes to Netflix on March 31.
