Quantum Leap

1995, New-Mexico. A top secret project called Quantum Leap was invented and constructed by a brilliant quantum physicist Dr. Sam Beckett. He managed to build a time machine that enables a person to leap into different times within his own lifetime. While testing this machine Sam prematurely steps into the project's accelerator and leaps into another time.

He finds himself leaping into someone else's time line, and soon discovers, with the help of the holographic (and sometimes helpful) Al, that he must help solve a major crisis within that person's life if he is to 'leap' again - into someone else's time-line, which he hopes will one day be his own.
