Worth

When an eccentric old neighbour dies and names Violet March in his will, she is even more surprised than his estranged and spoiled family. To make matters stranger, she learns that all must attend a pretend murder-mystery weekend for any to claim a share of the inheritance. Being a good sport under constant scrutiny and suspicion becomes trickier when she finds herself torn between the romantic attentions of both the deceased's "favourite" grand-nephew and the charming black sheep of the family. Loyalty forces her to favour the former, but when it is the latter who inherits the bulk of the estate, a grave case of mistaken identities is revealed leaving Violet to determine whether pride and an unwillingness to be labelled a gold-digger may stand in the way of the love of a lifetime.
