 Two grifters - boyish, likable Juan and hard-edged, scheming Marcos - meet by chance. Marcos, who seems to have cheated everyone he knows including his siblings, is missing his partner, so he offers to teach Juan tricks for a day. Juan accepts because he has some savings, but needs more to bribe a judge to release his father from prison. Marcos gets a call from an aging, ill ex-associate needing help to sell a forged set of rare stamps, the Nine Queens, to a businessman about to be deported (he can t take cash out of Argentina, but could take the stamps). When the con men have to improvise, Marcos asks Juan to use his savings to set up the deal. Is Juan about to be conned?
