And, needless to say, Zatanna's still cramping her style.
What's happened is this. Horny as ever, Supergirl's desperate to get down to some serious canoodling with a man she's met in a driving incident.
That man is Tony Martyn, a handsome and mustachioed member of the Peace Corps.
There's only one problem. Right now, he's in danger of becoming a member of the Peace Corpse because he's gone missing in the Himalayas.
In fact, there's another problem too.
And that's that Tony's also met Zatanna - and she's as keen to tickle Tony's tonsils as Supergirl is.
So, independently of each other, the two heroines set off to the Himalayas and soon find themselves at odds over just which of them should be rescuing the object of their desire.
It all comes to a head when they find themselves up against a giant snowman created by the mountain-living demon Orgox who's holding Tony captive.
Fortunately, after accidentally zapping each other instead of the snowman, it dawns on them to act like adults and team up against the the thing.
That dealt with, now all that's left for them to do is rescue Tony from Orgox and that's that.
Except it isn't because it turns out Tony doesn't have the hots for either of them and is an engaged man who can't wait to get home to his fiancée, leaving Zatanna and Supergirl to return home in a huff.
Personally, I'd have preferred it if Tony had turned out to be gay and not just engaged, just to really thwart their amorous designs but it's the 1970s, so I suppose the chances of that happening were always going to be low.
Flatmate count in this issue: Zero.
