Both anime are about test pilots that end up getting into more than they bargained for. There's some romance involved and haunting pasts. The main differance between the 2 is that Macross Plus focuses a lot on music where the other more on taking out the enemy Both are sure to please and you do not have to have seen the other series in their franchises in order to watch them.
One shouldn't really go in expecting much with the characters and plots in these two, especially when compared to other installments in both the Gundam/Macross series. But where these two OVA's excel at, they really shine - the production values, the nostalgic and incredible music, amazingly top notch animation and art for their time, and the insane action make them both worth seeing for the technical aspects alone. Both are sci-fi, mecha, and all that sort of thing, chances are if you like some of Macross or Gundam, you'll like both in many ways too.
Okajima Rokuro is a small-time salary man who is carrying documents for his company, when the ship he's traveling on is attacked by pirates. Kidnapped, he discovers to his dismay that his employers' main concern is to ensure the documents don't get into the wrong hands, even if it means sending the carrier to the bottom of the sea. Now, with his former life ruined and his kidnappers seeming comparatively friendly, "Rock" decides to join their merry band of mercenaries, and sets out with a new career to the shadier corners of the South China Sea.
Both of these shows deal with stories where it's hard to tell the good guys from the bad guys. No one is really evil in these shows, but noone is a saint either.
And they both have amazing action scenes!
