Thanks to the Amazon France listing for Scooby-Doo! Return to Zombie Island, we now have an official summary of the film. Translating the French description into English, here is what the summary says:
Seeking to leave their investigative career behind them, the Scooby-Doo team leaves for an all-expense paid trip on a mysterious - but strangely familiar - tropical island. Their journey will however take a new turn as soon as they meet the zombies that populate the island.
I'm a bit disappointed they're playing the "leave their career behind them" card again from Curse of the 13th Ghost, but nonetheless, it sounds somewhat interesting given how short the description was. I guess we'll just have to wait and see.
What are your thoughts on the summary for this film? Let me know in the comments!
