The men we might have been (смешанная)

Husbands and soulmates Tony, Steve, and Bucky never thought they'd wind up back in the Siberian Winter Soldier Bunker they destroyed years ago, but that's where they find themselves when a battle hurls them into an alternate dimension. Here in the MCU, the bunker's still standing, and there's a man inside with a video he claims will tear the Avengers apart.
And he's right.
Good thing the three of them aren't this dimension's Avengers.
