This week we find the Enterprise crew participating in an officer exchange program, while one of their own goes off on a Klingon vessel they receive an officer who has no idea what he's gotten himself into. All seems to be going well for Commander Riker, but things quickly take a turn that forces him to decide if he's loyal to the Enterprise or his new crew. Meanwhile the Enterprise's newest bridge crewman is walking a very fine line with Worf. Will Riker enjoy his time on a Klingon ship? Does Worf have the patience to not slam a crewman through the computer console? Will Riker fight his way to the Captain's chair? Will Wesley make the mistake of thinking all blue people look alike? Will Riker take a Klingon woman....or be taken by a Klingon one0? All these questions and more will be answered on this week's episode of Hailing Frequencies Open.
