The O.S.I. has learned that Beaumont, a dealer in stolen art, intends to steal a famous painting. To evade pursuit, he'll replace it with a copy. But the O.S.I. gets a break because they have Pierre Lambert, the forger Beaumont contacted to commission the forgery. But Lambert may not be entirely on the level, and if Beaumont discovers why Jaime has come to Paris, her O.S.I. career is likely to come to an abrupt end.
