Sam leaps into Ronald Miller, a legless Vietnam vet in a veterans' hospital who must save the life of a quadriplegic soldier while still keeping his wife from leaving him so that his eldest son can save a tank troop in the Gulf War.
August 10, 1968: Sam leaps into the body of Marine Corps Captain Ronald "Ron" Miller (leapee played by Michael Carpenter), who is in a Veterans Hospital having lost both of his legs in combat in Vietnam. His wife had met him in Tokyo when he was first evacuated from the war zone, and it's not apparent why Sam is there. Al thinks it's to reconcile with his wife since history records that has several children.
Sam wonders if he's there to help his hospital roommate, Sergeant Billy Johnson (Michael Boatman), who is now a quadriplegic. He seems to have given up on life refusing to have anything to do with his loving girlfriend. Al knows that Billy will commit suicide by drowning himself in the pool so Sam sets out to ensure that it doesn't happen. Sam also becomes close to Kiki Wilson (Jennifer Aniston), whose brother is MIA, and who also volunteers at the hospital. Her cheery attitude helps all of those around her - and it's also clear that she has taken a particular interest in Captain Miller.
