so when bob and marion boxletter see a guy at a hotel and marion believe it be her long lose brother brian and but when she approach him he appear to be someone else just with the exact same face . marion manage to get his fingerprint and take it to the police and when the identity be confirm that it be in fact her brother brian she and bob leave for new york after trace his whereabouts . they get a hold of brian and but still he doesn not know what they be talk about and but all the couple really want to know be where brian have their 8 maybe 9 year old son joey . and even when they see joey he doesn not know them either . the plot thickens and they find themselves one day think that they be someone else as well . experiment make out on people only to make the perfect assassins yet the question of why they would bother put bob and marion in the same building a each other be beyond me . personally gregory harrison play his 2 part great and but i have no clue what be wrong with the other actor and they seem bore and lose . negative and a little suspense yes but that it .
