There’s a lot going on here. First, we get some specific info about intergalactic travel. All the Trek adventures we’ve seen so far (except maybe a little of Where No Man Has Gone Before) has taken place here — within our own Milky Way Galaxy. To get to Andromeda would take thousands of years, even at warp speed, and there’s “nothing” in between the two galaxies. (I think that last fact is accurate. . .I think.) Anyway, some super beings who have assumed humanoid form (and what form!) need the Enterprise for a multigenerational trip back to Andromeda. You don’t like it, they’ll hit the garage door opener on their belt and freeze you. You try again and they’ll turn you into a cube and crush you (see below). The only way to foil the plan is to strike at the container the beings are in — their humanity! We must flummox them, anger them and, yes, teach them to love. The mega hottie who plays the main space chick basically says But what is love? by asking to be taught more about the “cultural mystique surrounding the biological function.” Classic.
