Marlene Dietrich stars as the unfaithful wife of a foreign diplomat in the sophisticated comedy Angel directed by Ernst Lubitsch. Lady Maria Barker (Dietrich) has the perfect life: a famous husband (Herbert Marshall), a stately English manor, and endless trips abroad. Unfortunately, the one thing that is missing - her husband's attention - leads to a short-lived affair with a dashing British stranger (Melvyn Douglas) in Paris who knows her only by the name "Angel". Though she tries to put the infidelity behind her, the whirlwind romance comes back to haunt Lady Barker when the Englishman turns out to be her husband's old military chum. Torn between her husband and her lover, she is forced to make an agonizing decision that may change her life forever.
