Sam Nesiac, salesman, believes he has the world's worst memory - "a mind like a sieve". Following an accident, Sam has a "dream" in which he enters his mind. There he meets Tracey, who is in charge of his memory department.

She demonstrates how Sam's memory works, its enormous potential, and the techniques he can use to improve his memory for names, phone numbers and appointments. On returning to reality, Sam begins to apply these techniques with increasing success.

The key to improving memory is summarised in the formula:

ATTENTION + INTENTION - TENSION = RETENTION

This film shows how memory works as a storage and retrieval system, and provides techniques for improving memory skills.
