Jimmy Barclay is in a bad mood. His dad asks why, and Jimmy responds that he was put in charge of the missionary fund-raiser for his Sunday school class. Dad says that since Jimmy has to do it, he might as well do his best. But Jimmy's first effort produces a poster, which shows a missionary being boiled in a pot by cannibals. So, George gives him some books on the subject-including one by Dan Isidro, missionary to the Miskito Indians in Nicaragua. Jimmy starts to read and soon falls asleep-only to wake up in with Dan in Nicaragua!

Jimmy and Dan are on their way to pick up a sick boy named Pablo and take him to the doctor. But they are met with setback after setback along the way. The battery in their jeep goes dead, they run out of gas, and soldiers threaten their lives. Even though they manage to get through all the problems, the situation is still hopeless for little Pablo. Jimmy is distraught. They have to do something to save him!

He awakens from his dream with those words on his lips and realizes that missionaries do much more than stand on corners and hand out tracts. Jimmy decides to do something to help them. He puts his creativity to work and comes up with the best fund-raiser the church has ever had: a Christmas party for missions. Everyone gives money, the party is a success, and Jimmy is stunned when a special guest arrives-the missionary Dan Isidro!
