Scarecrow and Mrs. King (1983)

A spy being chased hands a package to a divorced mom of two and tells her to give it to the man in the red hat. Trouble is, the train is full of men in red fezzes. That opening sets the tone: Kate Jackson's Amanda King ends up working for the Agency alongside Bruce Boxleitner's Lee Stetson, while keeping the job secret from her own family. It is gentler than the others here, closer to light romance than explosions, and the slow-burn partnership is what keeps fans going through all four seasons on CBS. Pick it for a night when you want adventure with more banter than gunfire.
