Family is lounging and playing outside in the pool area of their resort before the tsunami
The tsunami hits the resort while their at the pool and they eventually get separated
The mother & son are stranded in the tsunami waters full of trash & trees.
The father and two sons were stranded onto of their resort & help was notified, but the father stayed behind to find out if his wife and third son were still on the island. (This is an example of resiliency because besides the fact that they've already been through so much and he made the tough decision to leave his kids behind to find his wife and kids)
The family is all reunited in the hospital in the end. (This is an example of resiliency because regardless of what they've been through, they still made it a priority to be together in the end.)
