Exclusive: 'In Plain Sight' Eyes 'Dreams' Girl Rachel Boston

Is Marshall finally getting over his Mary issues on In Plain Sight? Probably not, but at least he’s found himself a nice distraction: American Dreams‘ Rachel Boston!

Sources confirm to TVLine exclusively that the 500 Days of Summer actress is joining the USA Network drama as Detective Abigal Chaffee, a recurring love interest for Fred Weller’s Mary-crushing U.S. Marshall.

Production on Sight‘s fourth season begins later this month in Albquerque.
