'Castle' Season 7 Spoilers: Watch Rick And Beckett Strike Gold In Honeymoon Episode Sneak Peek Video

It’s been one week since the “Castle” wedding, but the show and its fans are not done celebrating. Episode 7 of the ABC series, titled “Once Upon a Time in the West,” will feature Castle (Nathan Fillion) and Beckett’s (Stana Katic) honeymoon. The episode will also feature a new case, of course, but while they will be looking for a murderer, a new sneak peek video reveals the newlywed couple might find something even more surprising -- buried treasure.

The episode will send the couple on an unconventional honeymoon when, in the investigation of a murder, Castle and Beckett go undercover as honeymooners (wink, wink) at an Old West-themed resort town to get to the bottom of the case. Along the way, the two might get caught up in some not-so-undercover romance as well. However, more surprising is what Castle and Beckett find in a new sneak peek video for Season 7, episode 7.

In the video Castle and Beckett discover a secret underground passageway where, evidently, they are searching for a century-old stockpile of gold. While Beckett insists the gold is likely all gone, she is quickly proved wrong when Castle finds the buried treasure. While Beckett seems a bit uninterested, Castle has gold fever, getting awfully excited about their find.

Watch the sneak peek video below:

What will Castle and Beckett do with their newfound treasure? And what does it have to do with the murder case? Fans will have to tune in to the honeymoon episode to find out. “Once Upon a Time in the West” airs Monday, Nov. 17, at 10 p.m. EST on ABC.
