When a bolt of lightning hits a crane on Friday 13th, a bus full of
passengers crashes into a shop. We follow the events in the lives of the
passengers prior to the accident.
Bus conductor Alf and his driver Fred spend the day at the Derby and Alf
expresses his forebodings about working on Friday the 13th. One of the horses
they back is a winner, which makes Alf think perhaps the day won't be so bad
Mr Jackson plans to take his wife on a surprise cruise to celebrate their
wedding anniversary. He boards the bus after working late, little knowing that
his wife has left him that very day for a sleazy fellow named Max.
Cockney market trader Joe is being pursued by a detective, who believes he
has stolen a valuable china statue. Two Americans pose as antique dealers from
New York City and they travel with him, towards his lockup, on the bus.
Receiving a tip for a stock market certainty, Mr Wakefield asks his wife to
hand deliver a letter to his brokers. Afraid to admit to her husband that she
has forgotten, Flora Wakefield slips out of the house late at night, and catches
the bus towards Wimbledon Common.
Blake is blackmailing a young couple, Frank and Mary, and is travelling on
the bus with a cheque for £100 they have given him to keep their secret. Blake
knew Frank from a stint in prison and is threatening to tell Frank's employers
about his past.
Henpecked husband Ralph meets Dolly in a park. They flirt and kiss. When he
takes the bus home he discovers she has stolen his wallet. Smugly, the
blackmailer Blake pays his fare for him.
Chorus girl Millie argues with her jealous fiancé, Horace, who insists that
she give up her stage career when they marry. When Horace fails to meet Millie
at the stage door after work she boards the bus intending to take up a variety
agent's offer of supper at his house.
The aftermath of the accident. The bus driver and Alf are in hospital beds.
Alf receives attention from a glamorous nurse. Market trader Joe has also
survived the crash. He enjoys watching the detective and the two Americans
searching through the wreckage of the china shop, which includes the stolen
statue he was carrying on the bus. Mrs Wakefield and her stock-investing husband
laugh with relief about her forgetfulness, which has saved them from financial
ruin. Henpecked Ralph's wife makes a great fuss of him as he has been injured in
the crash; they are reconciled. Chorus girl Millie and her beau are happily
reunited. She has sprained her ankle in the crash, so cannot dance for a while.
Blake's blackmail victims receive a visit from a policeman who informs them that
he was killed in the crash, releasing them from worry. The cuckolded Mr Jackson
did not survive the accident.
Mrs Twigg and her nephew read about the crash in a newspaper. She observes
that they were extremely lucky to have got off the bus just before the crash.
The, nephew, however wisely notes that if the bus hadn't stopped to let them
off, the crash would never have happened.
