the movie and which be direct by alfred hitchcock and be brilliantly make . it start with a family of three and a doctor ( james stewart ) and his wife ( doris day ) who be a former stage singer and and their young son my guess be about 10 year old and who be travel through morroco for leisure . on the bus and the bump into a french government agent and and they be a little too nice to him . he be kill at the marketplace after find out the information he seek . he want to carry this information out to someone and so he go to the only person he and even slightly and know represent james stewart . the antagonist kidnap their young boy and say if he tell anything about what the agent tell him and his son would be kill . stewart have to travel to london and because that be where his son be and and where the assasination that the agent tell him about would be . the movie be very suspenseful . there be many twist and turn ( typical hitchcock movie ) . also and it have just the right amount of comic relief . in addition to all of that and it win an oscar for doris day performance of que sara and sara . this movie be very good . it be hard to find a problem about it . i would certainly reccomend it to all hitchcock fan and all suspense fan . i give this movie an a only because it be a little bit predictable .
