Wendell B. Harris -- he also wrote and directed this movie -- is bored with his life with his well-paying job with his father's company and his beautiful wife. So he reinvents himself as an exchange student at Yale, then as various other people. It's all remarkably easy for him.
He's playing William Douglas Street Jr., a real man who did exactly that. It's a remarkable performance, although after a while it becomes apparent that it is a performance; after all, Harris is acting here, and his ability to work in different registers is an actor's meat and potatoes.
Nonetheless, the movie itself is an interesting character study, as the character reveals himself as a very intelligent manic-depressive who grows bored with his successes. That's good scripting combined with good acting. I'm not too sure that the ending, which is probably lose to what happened, is good story-telling; the police come to arrest him and the story ends, like a Tex Avery cartoon.
In real life, Street kept the impersonations going for perhaps 46 years, false identities he assumed included those of a reporter for TIME magazine, a Houston Oilers wide receiver, an all-star football player from the University of Michigan, a physician at Henry Ford Hospital (in 1973), attorneys (1979 and 1980) and as a first-year medical student at Yale University. Staff at the Detroit Human Rights Department where he posed as an attorney volunteer found him skillful enough that "if he ever straightens out, we wouldn't mind having him back." What the movie doesn't mention is that he was caught kiting checks and extortion. He was sentenced in his mid-60s to three years on identity theft.
