The Mother (2003)

Toots and May's marriage is one of Toots being dependent on his wife. Shortly after Toots and May arrive in London to visit with their grown children Bobby and Paula and their respective children, Toots falls ill and dies. Toots' death brings to the surface the underlying strain that has always existed between May and both of her two children, and the unhappy lives they have all led. Now specifically with Paula, May is disapproving of her relationship with a construction worker named Darren. Not only does May think his occupation makes him beneath Paula, he's also a married man. Darren is in an unsatisfying marriage but doesn't want to leave it if only because of his son. Even after May gets to know and like Darren, she still encourages Paula to break up with him. The issue is is that May herself has fallen in love with Darren, the two who begin a sexual relationship…
