Hancock, a junior clerk in a City office for 19 years, receives a promotion when his army friends, who met at a reunion, place large orders with the firm. However, they are all fraudulent orders and Sid has the takings.

Hancock takes up entering newspaper competitions as a full time job. When he wins a few competitions, he is foolish enough to trust Sid to look after the money.

Hancock agrees to attend an identity parade at the local Police station. But when he is mistakenly picked out by three witnesses he decides to prove his innocence by recreating the crime.
