National Lampoon’s Christmas Vacation 2: Cousin Eddie’s Island Adventure

After leaving the Nevada bomb-test site, Eddie begins a new job at the Chicago Atomic Testing Agency, measuring brain waves for radioactivity. The family moves in with Audrey after the dirt farm is foreclosed and the RV is repossessed. Life moves toward Christmas as they adjust to a new normal.

Roy the chimpanzee outperforms Eddie in every cognitive test, leaving Eddie feeling inadequate at the agency. Officials become concerned about Eddie's position as budget cuts loom. The performance gap foreshadows Eddie's looming trouble, just before Christmas.

Budget cuts force Eddie to be fired from the agency, leaving him desperate to prove himself. He insults Roy, and the chimp bites him in response. The incident seals Eddie's humiliation and sets the stage for a drastic holiday plan.

As a preemptive countermeasure against any potential lawsuit, Professor Doornitz offers Eddie and his family an all-expenses-paid Christmas vacation to Maluka. Eddie, Catherine, and their son Third agree to go, joined by Uncle Nick and Audrey. The trip promises an escape from trouble and a chance for Eddie to prove himself elsewhere.

Eddie, Catherine, Third, Uncle Nick, and Audrey embark on the Christmas vacation to Maluka. The group leaves their old life behind and heads toward a tropical island adventure. The mood mixes optimism with the sting of Christmas being far from home.

The group is greeted on Maluka by guide Muka Luka Miki, who hosts a Christmas cookout for the newcomers. After the feast, they board a boat to tour nearby islands. The dynamic among the travelers hints at the family tensions and humor to come.

While Eddie tries his hand at fishing from the boat, he hooks a large shark that drags the vessel far from shore. Uncle Nick loses control and crashes the boat into a coral reef, further stranding them. The group realizes they are shipwrecked on a deserted island.

The castaways realize they must provide for themselves and start a fire while looking for food. Eddie takes the lead, determined to prove his manliness to his son Third. The island's dangers and isolation set the tone for a survival Christmas.

Chasing a wild pig, Eddie climbs a tree but is knocked down and drives his spear into a boar, accidentally killing it. He returns with the carcass to feed the group and earns a rare moment of pride from Third. The event becomes Eddie's makeshift proof of being a provider.

The group exchange handmade or regifted gifts as they celebrate Christmas on the island. Third and Eddie finish a grass hut that Eddie calls their first home that won't be foreclosed, but the hut collapses as soon as they close its door. The moment underscores the family's precarious situation.

Eddie signals for help and a sea plane arrives, piloted by Melbourne Jack. The pilot explains the island's name as King Halihalki and mentions a resort ten miles away, suggesting they could walk to safety. The news shifts the group's hope toward escape.

Jack suffers a severe concussion during the return attempt and passes out. The plane must be landed in the water, but Eddie manages a water landing with help from the Maluka tower, saving the family. The disaster turns into a rescue mission and a moment of gratitude.

Jessica arrives on Maluka to reconcile with Nick, indicating a turn in their complicated relationship. Her decision means the extended family remains together on the island for Christmas. The moments on Maluka begin to settle into a new normal.

Doornitz and Roy arrive with news of Eddie's old job offer. Eddie declines, revealing he has found a new calling as a pilot on Maluka, with Roy serving as his co-pilot. The ending hints at a new life for the family on their tropical paradise.
