Generate a question about the following movie plot: Rachel Marron (Whitney Houston) is an Academy Award-nominated music superstar who is being stalked and sent death threats. Things get dangerously out of hand when a bomb disguised as a doll explodes in her dressing room. Rachel's manager, Bill Devaney (Bill Cobbs), seeks the services of a professional bodyguard, Frank Farmer (Kevin Costner), to protect her.[7] He is a highly successful private bodyguard, mostly protecting corporate VIPs. Formerly he was a Secret Service agent who served as part of the presidential protection detail during two presidencies. Frank is reluctant to accept the offer to guard Rachel as he sees her as a spoiled diva who is oblivious to the threats against her life. Frank's concerns are quickly realized when Rachel looks upon Frank as being paranoid and his extensive protection techniques as intrusive. Rachel's existing bodyguard Tony (Mike Starr) resents Frank's presence. But at a concert where Rachel is performing a riot breaks out, and Frank rescues her from danger. As a result, the two develop a closer relationship. Frank tries to remain professional, but the two sleep together. However, recognizing that this compromises his ability to protect his client, Frank breaks off their affair. Hurt, Rachel begins to defy Frank's painstaking security measures. She even goes as far as attempting to sleep with his former Secret Service colleague Greg Portman (Tomas Arana). But after she has personal contact with her stalker via a threatening phone call, Rachel realizes that she must put her trust in Frank ahead of her own desire for personal gratification. She finally recognizes the seriousness of the situation and cancels the rest of her tour. Frank, Rachel, Rachel's driver Henry (Christopher Birt), Rachel's son Fletcher (DeVaughn Nixon), and her sister Nicki (Michele Lamar Richards) then travel to a large lakefront cabin in the mountains, the home of Frank's father, Herb (Ralph Waite). The next day, Fletcher is almost killed when a bomb explodes inside the boat he rode moments before....
Who will Frank protect in his next assignment?
