When the slick and calculating Barret (Ben Caplan) offers Isaac (Jonathan French) a five-day job "babysitting" Barret's adult niece Olga, who needs "company" at her "isolated" childhood home, Isaac, a drifter suffering from some kind of amnesia and the mental fog that goes with it, is confused. Barret claims to be an old friend, but Isaac has no memory of him. Also, why is this supposed old friend offering him so much money to hang out with a woman clearly too old to need a "babysitter"? Isaac says, baffled, "There's got to be more to it than that." Suddenly, the title card appears, in jagged letters: "CAVEAT."
