Completely Similar

American Detective, Daniel O'Leary has hired a British Detective, Miles O'Keef, A.K.A., 'The Welsh Dragon.
His assignment: To take up residence in the O'Leary home, to act in pretense in becoming Dan's Sister,
Tegan O'leary's detective trainer, in order to sabotage his sister's relationship to Paul, her womanizing fiancee.
Dan and Tegan's parents, Samual and Sue O"Leary, are infatuated with anything Welsh, trying to encourage
their daughter to dump her flirtatious fiancee and 'grab-n-run' with Miles instead. But to piece together their
unforeseen attraction to each other, while the differences of incomprehensible slang leads to a clueless
humor, that is completely similar.
