Alvin is from England and visits his grandparents in South Africa for the Christmas season. While travelling, his parents point out the different types of engineering fields available. Upon their arrival, Alvin's granddad surprises him and his little sister with a gift. During his visit, Alvin's grandparents explain what each engineer does, such as, aviation, mechanical, chemical, marine, electrical and civil engineering. At the end of his holiday, Alvin plays with his Christmas presents and chooses the type of engineer he wants to become one day.
