Winter is finally dying away, and the sun peeks out from behind the clouds.
That means that it’s time for a PAYDAY Spring Break again.

And this spring comes with something extra. Especially for Jiro who’s finding a clue to to the whereabouts of his son, Kento. A small and maybe insignificant clue, but still. By pressuring Bain, the PAYDAY gang manages to get him to devise a plan. A plan for getting Kento back. But as per usual, it’s not gonna be easy.
