Sommarnattens leende (1955)

A small town at the turn of the century. Lawer Fredrik Egerman has an ingénue-wife, Anne, and a grown-up son, Henrik, from an earlier marriage. His wife is still untouched, and instead he meets his former mistress Desiree after her performance at the theatre. They leave the theatre together and Egerman falls in one of the puddles. Desiree takes him to her home and Egerman changes into a night-shirt, owned by count Malcolm, Desirees present lover. Suddenly the count comes for a visit and throws Egerman out.
