When a group of bad guys steal the Mystery Machine, the gang ends up stranded in the desert.
Daphne wants to investigate an abandoned diner “to see if they have Wi-Fi inside” and they stumble upon Axl, who somehow already knows Shaggy and Scooby. The trio even have a secret handshake.
“What’s up mystery gang,” Rose says. “I was starting to think you guys were a no show.”
When friend after friend starts disappearing, it’s down to Axl, Shaggy and Scooby to solve the mystery.
