Logline: Soon to be married couple John Rossi & Linda Banks are both very aware of their respective sibling’s disastrous dating history. In order to avert what would certainly be an ugly emanate break-up, they make their brother and sister, Kevin & Lucy, both swear that they’ll never hook-up, thinking that this will save them from any potential uncomfortable family situations in the future. But after meeting, commitment-phobic Kevin, and obsessive-compulsive Lucy, both agree that this is one promise that was made to be broken.
