"MacGyver (Richard Dean Anderson) is a modern-day ""knight-errant,"" a person people turn to in a crisis. He has a penchant for arriving on the scene in the eleventh hour, when the clock is ticking ominously and innocent lives often are at stake. MacGyver is a packrat, collecting ordinary items of seemingly little value and stashing them in his knapsack ""for a rainy day."" And it is these same items that he uses to improvise his way out of trouble. MacGyver's ingenius solutions to seemingly insurmountable problems may seem like ""gee-whiz"" science fiction but they are not - it's all based on scientific fact."
