Blue for a Boy (1970)

A married woman discovers her husband is having an affair with a male prostitute and wants to meet the lover to get answers. However, her plans are interrupted when she gets a heart-stopping call from the hospital — her husband had a stroke and is lying unconscious. The wife and the lover — who fell in love with the husband — both rush to the hospital, and the remainder of the film highlights the dynamic of the two grappling with their situation as they both wait for the husband to recover in the ICU.
