Castle (Nathan Fillion) and Beckett (Stana Katic) are slated to team up with a Hong Kong detective who may not be who she seems in the next episode of ABC's Castle.

'Castle' Stars Nathan Fillion & Stana Katic's Future With Show Still Up In The Air?

ABC has released a new plot synopsis for the next episode of Castle, which is intriguingly titled Hong Kong Hustle.

"After a man is mysteriously murdered in a park, Castle and Beckett team up with a competitive, high-powered female detective from Hong Kong, who has information about the victim," the synopsis reads. "But as Beckett digs deeper into the case, she realizes neither her Hong Kong colleague nor the victim may be quite who they seem."

The episode is set to feature Linda Park (Star Trek: Enterprise) as Inspector Zhang, who appears to be the Hong Kong female detective. Hong Kong Hustle airs Monday, March 16 at 10 p.m. ET/PT on ABC.

Park's casting in Castle had previously been reported by TVLine, who said that Zhang is a detective who Beckett is "paired up with, somewhat unwillingly."

Apparently Park's character is similar to Beckett, "except even better, so that puts Beckett in a bit of a tailspin, to be dealing with somebody who in her eyes is more accomplished and proficient."

Since Inspector Zhang is someone who isn't as she seems, it will be interesting to see how Beckett handles the whole situation.

Castle airs Mondays at 10 p.m. ET/PT on ABC.
