Following a missed wisdom save, the target will cease caring about the activities they are currently engaged in. They will defend themselves if attacked, and they will not let someone pickpocket them, physically move them, cast a spell on them, etc., if they can resist. At the DM's discretion, a target may be able to summon the ability to defend someone very dear to them as well--spouse, child, close friend, etc. But they will make no attacks or cast any non-defensive spells in any case, and will otherwise not attempt to intervene in the actions of others. A guard will let people walk right past his guard post, for example, although he is likely to tell someone about it later if asked. Every round in which the target is attacked allows them another save versus the spell. A successful save immediately ends the effects.
