The obvious play is the obvious play -- spade Ace, then duck.
There is, however, a conspiracy theory justification for an unusual line. The opening lead is strange. With Kxxx and out, I'd be inclined to start with the King, to maintain lead flexibility in case a switch through dummy is needed. This seems expected at this level. The failure to pursue this line suggests that LHO is not actually Kxxx and out. (A weak suggestion, but let's play with it.)
The next "clue" in the conspiracy theory is the heart return. If RHO holds both kings, and his spade is short, he should be able to visualize the ending and will realize that he is in trouble. With KJ of diamonds, a juicy trick play looks promising, namely the return at trick two of the diamond Jack. This offers some prospect for a hop of the Ace by Declarer. Declarer might be lulled into believing that 5♣ is hopeless, but hopping Ace allows the contract to at least be held to -1. This seems remote, but I am pursuing a conspiracy theory, after all.
So, perhaps Opener, at IMP's, actually holds 109xx-AQxxx-KJ-xx? Plausible, a seven-loser hand with both majors. Now, a simple spade finesse, then the Ace, drops the King. I cross to the Jack, back to dummy, ruff a spade, and then play Ace and out a diamond.
Naaaaaaaaaaaah!!! Ace and out a spade.
