From IMDB:

“Alibi” is a thriller with a bit of romance and touches of black humour along the way. Greg is discovered with the dead body of his wife’s lover by Marcey, a public servant moonlighting as a waitress at a party thrown by Greg for he and his wife’s wedding anniversary. Marcey sets about ‘organising’ th e slightly neurotic Greg in his attempts to cover up the ‘accident’.

From Acorn TV (Offerings limited to entire British Empire) you can stream this funny series of just three episodes, each episode lasting one hour.

Michael Kitchen plays Greg.  You may recall him as Christopher Foyle in the TV series “Foyle’s War”.  Greg is a slightly befuddled entrepreneur caught up in an unsuspected affair.

Sophie Okonedo played Tatiana Rusesabagina in “Hotel Rwanda”. Here she plays a supremely inventive liar who attempts to help Greg out of his trap. Her facial expressions are remarkable.

Phyllis Logan played the head housekeeper Mrs. Hughes in “Downton Abbey”. Here she is Greg’s scheming wife.

British humor is often slapstick. Nonetheless, just relax and enjoy the fun.
