As dimensional portals bring refugees from an another earth, a disillusioned border agent encounters his alternate-earth daughter and becomes torn between following orders, or protecting an alternate world from annihilation.

One other thought:? I suggest narrowing the focus of his objective goal in the logline to merely saving his daughter.? That has to be the most paramount goal in any parent's mind, right?? ?And it's good enough for plotting purposes.

I like to view a plot as a poker game.? Initially, the protagonist only has to put in a few chips [risk, effort)]to get into the game.? The major plot points are betting rounds, where he must see and raise, put more and more? and more chips into the pot [escalating risk, effort] to stay in the game.? Ultimately, he will have to push every chip into the pot.

Transposing the poker analogy to your story, it could be that initially he thinks he can rescue his? daughter with a minimum? bet [risk and effort].? (And only his daughter:? not because he's selfish but because he's just one man; he doesn't have the power, the ways and means, to rescue every one.)

Only to discover he has to make bigger bets [risk, effort].? Finally, he realizes that the only way he can save his daughter is to push every chip into the pot [including his life] to incite a rebellion that liberates the others.

fwiw
