In a nutshell: Danny returned, showing signs of PTSD and immediately asked Mary to marry him....all the time acting very strange and out of it. James Caan and his group are following a couple strange fellows around the casino who are acting like goofs, but are up to something....Mary realizes things aren't right with Danny and says she needs to think about marriage...he gets enraged and takes off and they can't find him...James Caan finds Danny in a hotel room with loaded rifle, and they have a "talk" about the war, Danny hasn't slept in a long time because there is "no one to watch his back", so James tells him he understands and has been there done that...tells him to go get shower...you see open terrace door, and he thinks "oh is he out there going to jump" ... when we see Danny passed out asleep on the bed...James sits with him to watch over him, Mary comes in room also, they get the goofy guys and foil there attempt to steal credit card numbers and such...and that is where we were left...I'm sure I've left out something...oh yes, the other gals were arguing about letting morticians have a private party at the hotel, can't think of the name ... oh yeah, Mystique, but they do and it is kinda funny with coffins and such and all that works out fine too.
whew....I'm worn out...hope this helps
