“1964″ — Life has changed on a dime for the crew of Pan Am. Since President Kennedy’s assassination and as New Year’s Eve approaches for the start of 1964, everyone’s lives are hurtling towards new starts: Colette is caught up in a whirlwind courtship with a foreign prince, and Dean is still kicking himself over losing her; Amanda and Ted’s wedding plans are racing forward, thrilling his family, but making him more nervous by the day; Kate’s spy supervisor, Richard, is shot and she tries to figure out whether he or someone else is a double agent — He warns her that the first person to ask her how he is doing will be the double agent, but the first person who does is the one person she never imagined; and Amanda makes Laura a startling offer. Meanwhile, Broyles puts Maggie in a life-threatening position-which sparks a major attraction to him — Laura forges on, still loving the man she can’t have, and Dean is put on trial for the decisions he made during the Haiti landing, on the Season Finale of “Pan Am,” SUNDAY, FEBRUARY 19 (10:01-11:00 p.m., ET) on the ABC Television Network.
